Improve test runner discoverability

Show all listed buffers in a tabline (current bufnr highlighted, modified
marker '+'), and reserve a permanent signcolumn so width doesn't jitter when
gitgutter/ALE/LSP signs come and go.

- ui.vim: TLBuild() + TabLine{,Sel,Fill} hl groups via ColorScheme autocmd;
  set signcolumn=yes for non-TTY (overrides core.vim's previous logic)
- core.vim: drop non-TTY signcolumn branch (centralized in ui.vim)

 # Changelog
 
-All notable changes to chopsticks are documented here.
-
----
-
-## [1.0.0] - 2026-03-29
-
-First stable release. Full-stack engineering environment out of the box — automatic
-installation, tiered LSP, TTY fallback, and coverage for 14 languages.
+## Unreleased
 
 ### Added
-- **Arch Linux support** in `install.sh` — pacman branch for all system tools
-- **`hadolint`** added to system tools installation (Dockerfile linting)
-- **`staticcheck`** added to Go tools (replaces archived `golint`)
-- **`yamllint`** added to pip tools (YAML linting)
-- **`coc-settings.json`** — configures `marksman` as Markdown LSP for CoC via
-  `languageserver` entry; symlinked automatically by `install.sh`
-- **pip3 bootstrap** in `install.sh` — auto-installs pip3 when python3 is present
-  but pip3 is absent (common on Ubuntu minimal images)
-- **9 named augroups** in `.vimrc` — all loose `autocmd` statements now wrapped
-  with `autocmd!` to prevent doubling on `:source $MYVIMRC`:
-  `ChopstickTabHistory`, `ChopstickResize`, `ChopstickStdin`, `CocHighlight`,
-  `ChopstickCleanup`, `ChopstickFiletype`, `ChopstickTTYLargeFile`,
-  `ChopstickWhichKey`, `ChopstickStartify`
-- **TTY-safe plugin install** — `vim +PlugInstall +qall </dev/null` prevents
-  Vim from blocking in non-interactive/piped environments
 
-### Changed
-- SQL tooling unified to **`sqlfluff`** (pip) — `sqlfmt` removed from npm section
-- Go linter changed from `golint` (archived 2023) to **`staticcheck`**
-- Markdown LSP changed from broken `coc-marksman` (npm) to **`marksman`** binary
-  configured via `coc-settings.json`
+- `~/.config/chopsticks.vim` local pre-load config for profile and user choices
+- `g:chopsticks_enable_markdown_preview` to control Previm independently
+- `g:chopsticks_profile` with `minimal`, `engineer`, and `full` profiles
+- `.markdownlint.json` aligned with the project's README/changelog style
+- `:ChopsticksStatus` diagnostic command — checks system tools, LSP servers, linters, formatters
+- `,af` toggle format-on-save (ALE `fix_on_save`)
+- `,gL` git log graph (last 20 commits)
+- `,gC` FZF git commits search, `,gB` buffer commits
+- Interactive installer profile selection for `minimal`, `engineer`, and `full`
+- `install.sh --profile=minimal|engineer|full` for scripted profile selection
+- `install.sh --dry-run` to show the resolved profile/config path without writes
+- `install.sh --configure-only` to update local profile config without reinstalling
+- `get.sh --dry-run` for safe bootstrap previews before clone/update/install
+- `CHOPSTICKS_DEST=/absolute/path` to test or install the bootstrap target elsewhere
+- `scripts/test.sh` local test runner reused by GitHub Actions
+- `scripts/test.sh quick`, `--help`, and `list` for easier local test discovery
 
 ### Fixed
-- **vim-go startup hang** on Arch Linux — removed `:GoUpdateBinaries` post-install
-  hook; set `g:go_gopls_enabled = 0` to prevent conflict with `coc-go`
-- **E495 errors** (`<afile>` in special buffers) — all `<afile>` usages guarded
-  with `!empty(expand('<afile>'))` and `empty(&buftype)` checks
-- **`g:go_def_mode` conflict** — now conditional: uses `gopls` when CoC active,
-  `godef` when vim-lsp active (avoids error when gopls is disabled)
-- **vim startup UX** — NERDTree + Startify layout for `vim .` and bare `vim`
-- **`coc-marksman` silent failure** — package does not exist on npm; replaced with
-  native `languageserver` configuration in `coc-settings.json`
-- **CoC startup warning** in no-node environments — `g:coc_start_at_startup = 0`
-  and `g:coc_disable_startup_warning = 1` set when `g:use_coc = 0`
 
----
+- `g:loaded_logipat` typo → `g:loaded_logiPat` — logiPat was loading fully (0.478ms wasted)
+- `get.sh` now refuses to update an existing `~/.vim` git repo unless its
+  origin is chopsticks
+- Large file protection now stays active after filetype and syntax autocommands
+- `g:ale_fix_on_save = 0` in local config is now respected
+- Local config now respects absolute `XDG_CONFIG_HOME` instead of hardcoding
+  `~/.config`
 
-## [0.9.0] - 2026-02-21
+### Changed
+
+- `,?` cheat sheet is now profile-aware and hides LSP/ALE/preview/UndoTree keys
+  when those features are disabled
+- Module reload/source paths now use `fnameescape()` so installs in paths with
+  spaces are handled correctly
+- CI now verifies path-safe module loading, the local config hook, and
+  minimal-profile cheat sheet output
+- Markdown now opens in quiet writing mode by default: no real-time markdownlint,
+  no Marksman LSP, no spell noise, no conceal, no sign column, and no realtime preview
+- Native `s` is no longer shadowed by EasyMotion; use `,S` for the two-character jump
+- `,w` now uses a normal `:write` instead of forced `:write!`
+- Swap files are enabled again and stored under `~/.vim/.swap` for crash recovery
+- Installer defaults are slimmer: only core search tools stay selected by default;
+  language and lint suites are opt-in
+- `:ChopsticksStatus` now respects disabled LSP/lint profiles instead of reporting
+  intentionally disabled tools as missing
+- `,sv` now clears the load guard before sourcing `$MYVIMRC`
+- CI now verifies key plugin directories, Markdown quiet defaults, markdownlint,
+  and an explicit startup-time threshold
+- Installer plugin validation now checks every plugin required by the active profile
+- The optional tool menu now hides LSP/lint suites in `minimal` and selects
+  Marksman by default in `full`
+- tmux integration is written as a managed block so future installer runs can
+  update it without appending duplicate bindings
+- Installer cleanup now restores the cursor after interrupted checkbox menus
+- Bootstrap dry-run now refuses unrelated existing git repos before any writes
+- CI now shares shell, installer, bootstrap, docs, and Vim smoke checks with
+  the local test runner
+- CI now checks the test runner help and group-list commands
+- Skip 2 more built-in plugins: openPlugin, manpager (10 → 12 total)
+- Remove deprecated `set ttyfast` (no-op since Vim 8)
+- Add `grepprg=rg --vimgrep` — `:grep` now uses ripgrep + quickfix
+- Add `diffopt` with histogram algorithm and indent-heuristic
+- Consolidate FZF Rg/RgWord/GFiles commands (DRY refactor)
+- vim-tmux-navigator: conditional load (only inside tmux), fallback `Ctrl+hjkl` mappings outside
+- Add `Ctrl+hjkl` window navigation fallback when tmux-navigator not loaded
+
+## 2.1.0 — 2025-04-22
 
 ### Added
-- **Full-stack language coverage** — LSP, lint, and format for: Python,
-  JavaScript, TypeScript, Go, Rust, Shell, YAML, HTML, CSS/SCSS, Less,
-  JSON, Markdown, SQL, Dockerfile
-- **`install.sh` overhaul** — automated installation of system tools, npm tools,
-  pip tools, Go tools, and CoC language server extensions with platform detection
-  and interactive prompts; `--yes` flag for non-interactive mode
-- **vim-startify** startup screen with dynamic header (version, cwd, git branch)
-- **vim-which-key** keybinding popup on `,` + 500ms pause
-- **Startup layout** — `vim .` opens NERDTree left + Startify right; bare `vim`
-  opens Startify with NERDTree alongside
-- **Session management** via vim-obsession + vim-prosession
-- **Large file handling** — syntax and undo disabled for files > 10 MB
-- **Project-local config** — `.vimrc` in project root auto-loaded via `set exrc`
-- **Persistent undo** — `~/.vim/.undo/` with `undolevels=1000`
+
+- Cheat sheet (`,?`) — vertical sidebar, one key per line, section headers
+- Previm markdown preview restored (lazy-loaded, `,mp`)
+- `:LspInstallServer` added to cheat sheet
 
 ### Changed
-- Tiered LSP backend: CoC (Node.js) preferred, vim-lsp (no Node.js) as fallback
-- All CoC and vim-lsp keybindings unified (`gd`, `K`, `[g`/`]g`, `,rn`, `,ca`)
-- ALE `fix_on_save` disabled when vim-lsp active (prevents double-format)
-- NERDTree autocmd wrapped in `augroup NERDTreeAutoClose`
 
-### Fixed
-- Multiple leader key conflicts resolved (`,ad`, `,cd`, `,cp`, `,sp`, `,t`)
-- CtrlP removed (redundant with FZF)
-- Duplicate `set` options cleaned up
-- `<leader>A` dead mapping (no alternate-file plugin) removed
+- Plugin count: 25 (restored previm, dropped 5 bloat plugins)
+- QUICKSTART updated — removed stale references, improved first-launch guidance

+
+## Rules
+
+1. **No Node.js dependencies.** The LSP engine is pure VimScript. Some language servers need Node — that's fine. The config itself must not.
+2. **Startup matters.** Run `vim -u .vimrc -i NONE --startuptime /tmp/s.log -es -N -c qa!` before and after. If your change adds >1ms, it needs a good reason.
+3. **Works on TTY.** Test over SSH. If it breaks in a terminal without true color, fix it or gate it behind `g:is_tty`.
+4. **One module, one concern.** Don't put git config in lsp.vim.
+
+## Adding a plugin
+
+1. Add the `Plug` line to `modules/plugins.vim`
+2. If it's not needed at startup, lazy-load it: `Plug 'foo/bar', { 'on': 'FooCommand' }`
+3. Put config in the appropriate module
+4. Update the cheat sheet in `modules/tools.vim` if you add keybindings
+5. Run `scripts/test.sh vim` locally after installing plugins
+6. Test on both macOS and Linux when changing terminal or package-manager behavior
+
+## Local tests
+
+```bash
+scripts/test.sh --help
+scripts/test.sh quick
+scripts/test.sh vim
+```
+
+`scripts/test.sh quick` runs shell, docs, installer, and bootstrap checks without requiring Vim plugins.
+`scripts/test.sh vim` expects plugins to be installed under `~/.vim/plugged`.
+Use `STARTUP_LIMIT_MS=150 scripts/test.sh vim` to match CI's startup threshold.
+
+## Reporting bugs
+
+Open an issue. Include:
+
+- OS and Vim version
+- Whether you're on SSH/TTY
+- Steps to reproduce
+
+## Code style
+
+- Named augroups with `autocmd!`
+- No comments explaining _what_ — only _why_
+- `exists('g:plugs["..."]')` guards for plugin-dependent config
+- Test with `scripts/test.sh vim`

 # Quick Start
 
-Five minutes from zero to a working Vim engineering environment.
+Five minutes from zero to a working Vim setup.
 
----
-
-## Step 1: Install
+## Install
 
 ```bash
-git clone https://github.com/m1ngsama/chopsticks.git ~/.vim
-cd ~/.vim && ./install.sh
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash -s -- --profile=minimal
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash -s -- --dry-run --profile=full
 ```
 
-The script handles everything: symlinks, vim-plug, plugins, and all tools.
-It detects your OS (macOS/Debian/Arch/Fedora) and installs what it can automatically.
+Open vim. First launch auto-installs plugins — **wait 30-60s, don't close vim**. Restart when done.
 
-**Non-interactive (CI / server):**
-```bash
-./install.sh --yes
-```
+Default profile is `engineer`. Interactive installs ask for a profile first;
+`--profile=minimal`, `--profile=engineer`, or `--profile=full` selects it
+without prompting. You can later put `let g:chopsticks_profile = 'minimal'` in
+`${XDG_CONFIG_HOME:-~/.config}/chopsticks.vim` for a smaller core-only setup,
+or use `full` for the heavier Markdown/LSP feedback.
 
----
-
-## Step 2: Open Vim
+To switch later without reinstalling anything:
 
 ```bash
-vim
+cd ~/.vim && ./install.sh --configure-only --profile=full
 ```
 
-The startup screen (vim-startify) shows recent files and sessions.
-Press `Ctrl+p` to find a file, or just type a path.
+## Modes
 
-To open a project:
-```bash
-vim .        # NERDTree on left, Startify on right
-vim myfile   # opens file directly
-```
+| Mode   | Enter           | Leave         |
+| ------ | --------------- | ------------- |
+| Normal | startup default | —             |
+| Insert | `i` / `a` / `o` | `Esc` or `jk` |
+| Visual | `v` / `V`       | `Esc`         |
 
----
-
-## Step 3: Set Up LSP (pick your path)
-
-### Path A: With Node.js (CoC — full LSP)
-
-```bash
-node --version   # must be >= 14.14
-```
-
-Inside Vim, install language servers for your stack:
-
-```vim
-:CocInstall coc-pyright coc-tsserver coc-go coc-rust-analyzer
-```
-
-Or let `install.sh` do it — it asks during setup.
-
-### Path B: Without Node.js (vim-lsp — no dependencies)
-
-Open a source file, then run:
-
-```vim
-:LspInstallServer
-```
-
-This auto-detects and installs the correct language server for the current filetype.

+
+## Why
+
+You SSH into a server. You need to edit code. You want LSP, fuzzy find, git integration, format-on-save — not a 20-minute setup.
+
+chopsticks gives you a production-ready Vim config in one command. Pure VimScript — no Node.js for the core. Degrades gracefully on TTY. Works the same on your MacBook and your headless Arch box.
+
+**24–25 plugins** (tmux-navigator loads only inside tmux), LSP, linting, and a hand-built statusline. No bloat, no decorations, just tools.
+
+## What's in the box
+
+| Feature           | Description                                                                                                                                                    |
+| ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **LSP**           | completion, go-to-def, hover, rename, code actions — pure VimScript ([vim-lsp](https://github.com/prabirshrestha/vim-lsp))                                     |
+| **Lint + format** | [ALE](https://github.com/dense-analysis/ale) runs black, prettier, goimports, rustfmt on save                                                                  |
+| **Fuzzy find**    | files, buffers, grep, tags, marks, commands — [FZF](https://github.com/junegunn/fzf.vim)                                                                       |
+| **Git**           | status, diff, blame, push, pull, conflict markers — [fugitive](https://github.com/tpope/vim-fugitive) + [gitgutter](https://github.com/airblade/vim-gitgutter) |
+| **Run file**      | `,cr` — auto-detects Python, Go, Rust, JS, C, Shell, and more                                                                                                  |
+| **Markdown**      | quiet writing defaults, browser preview (`,mp`), table of contents (`,mt`)                                                                                     |
+| **Diagnostics**   | `:ChopsticksStatus` — see what's installed, what's missing, how to fix it                                                                                      |
+| **TTY-aware**     | degrades gracefully on SSH, console, slow links — never breaks                                                                                                 |
+
+## Install
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash -s -- --profile=minimal
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash -s -- --dry-run --profile=full
+```
+
+Or manually:
 
 ```bash
 git clone https://github.com/m1ngsama/chopsticks.git ~/.vim
-cd ~/.vim && ./install.sh
+cd ~/.vim && ./install.sh --profile=engineer
 ```
 
-See [QUICKSTART.md](QUICKSTART.md) for the 5-minute guide.
+Supports macOS (brew), Debian/Ubuntu (apt), Arch (pacman), Fedora (dnf).
+Set `CHOPSTICKS_DEST=/absolute/path` before running `get.sh` to install
+somewhere other than `~/.vim`.
 
----
+First launch installs plugins automatically (30-60s). Restart vim when done.
+Use `./install.sh --dry-run --profile=full` to inspect the resolved profile and
+config path without changing files. Use `./install.sh --configure-only
+--profile=minimal` to switch profiles without reinstalling plugins or tools.
 
-## Design Principles
+## Profiles
 
-- **KISS** — No icon fonts, no unicode glyphs, plain ASCII throughout
-- **Tiered LSP** — CoC (full) with vim-lsp fallback; works with or without Node.js
-- **TTY-aware** — Automatic detection and optimization for console/SSH environments
-- **Engineering-first** — Git workflow, session management, project-local config
-- **Batteries included** — `install.sh` handles all dependencies automatically
-
----
-
-## Requirements
-
-| Requirement | Minimum | Notes |
-|-------------|---------|-------|
-| Vim | 8.0+ | vim9script not required |
-| git | any | For cloning and fugitive |
-| curl | any | For vim-plug auto-install |
-| Node.js | 14.14+ | Optional — enables CoC LSP |
-| ripgrep (rg) | any | Optional — enables `:Rg` search |
-| fzf | any | Optional — enables `Ctrl+p` fuzzy search |
-| ctags | any | Optional — enables `F8` tag browser |
-
----
-
-## Installation
-
-### Automatic (recommended)
-
-```bash
-git clone https://github.com/m1ngsama/chopsticks.git ~/.vim
-cd ~/.vim
-./install.sh
-```
-
-The installer:
-1. Checks Vim version and detects OS / package managers
-2. Backs up any existing `~/.vimrc` (timestamped)
-3. Creates symlinks: `~/.vimrc -> ~/.vim/.vimrc` and `~/.vim/coc-settings.json`
-4. Installs vim-plug and runs `:PlugInstall`
-5. Optionally installs system tools, language tools, and CoC extensions
-
-Supported platforms: **macOS** (Homebrew), **Debian/Ubuntu** (apt), **Arch Linux** (pacman), **Fedora** (dnf).
-
-Use `--yes` for non-interactive / CI environments:
-
-```bash
-./install.sh --yes
-```
-
-### Manual
-
-```bash
-git clone https://github.com/m1ngsama/chopsticks.git ~/.vim
-ln -sf ~/.vim/.vimrc ~/.vimrc
-ln -sf ~/.vim/coc-settings.json ~/.vim/coc-settings.json
-curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
-    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
-vim +PlugInstall +qall </dev/null
-```
-
----
-
-## LSP: Tiered Backend System
-
-Code intelligence is provided by one of two backends, selected automatically:
-
-| Condition | Backend | Features |
-|-----------|---------|----------|
-| Vim 8.0.1453+ AND Node.js 14.14+ | **CoC** | Full LSP, snippets, extensions ecosystem |
-| Vim 8.0+ (no Node.js) | **vim-lsp** | LSP via language server binaries, asyncomplete |
-| Any Vim | **ALE** | Linting and auto-fix (always active) |
-
-Both backends expose identical key mappings: `gd`, `K`, `[g`, `]g`, `<leader>rn`, `<leader>ca`.
-
-### CoC setup (with Node.js)
-
-Install language server extensions from inside Vim:
+Default profile: `engineer`. Interactive installs ask for this profile before
+plugins are installed; `--profile=minimal`, `--profile=engineer`, or
+`--profile=full` selects it without prompting. `--yes` keeps the existing local
+profile or uses `engineer`.
 
 ```vim
-:CocInstall coc-pyright       " Python
-:CocInstall coc-tsserver      " JavaScript / TypeScript
-:CocInstall coc-go            " Go
-:CocInstall coc-rust-analyzer " Rust
-:CocInstall coc-json coc-yaml " JSON, YAML
-:CocInstall coc-html coc-css  " HTML, CSS
-:CocInstall coc-sh            " Shell
-:CocInstall coc-sql           " SQL
+" Put this in ${XDG_CONFIG_HOME:-~/.config}/chopsticks.vim.
+let g:chopsticks_profile = 'minimal'   " core navigation/editing/git/markdown
+let g:chopsticks_profile = 'engineer'  " default: LSP, ALE, syntax extras
+let g:chopsticks_profile = 'full'      " engineer + heavier Markdown feedback
 ```
 
-`install.sh` installs all of the above automatically when prompted.
+`minimal` avoids LSP, ALE, completion plugins, extra language syntax plugins,
+Startify, UndoTree, and browser Markdown preview. `full` keeps those and opts
+into Markdown lint, format, spell, conceal, Marksman, and LSP virtual text.
 
-**Markdown LSP** — `marksman` is configured via `coc-settings.json` (not a CoC
-extension — install `marksman` binary via `brew install marksman` or download from
-[releases](https://github.com/artempyanykh/marksman/releases)).
+Project updates leave `~/.config/chopsticks.vim` alone, so put local choices
+there instead of editing the managed `.vimrc`. The `,?` cheat sheet follows the
+active profile and only shows keys for enabled features.
 
-### vim-lsp setup (without Node.js)
+## Keys
 
-Install language server binaries for your languages, then run:
+Leader: `,`
 
-```vim
-:LspInstallServer   " auto-installs the right server for the current filetype
+```
+Ctrl+p    fuzzy find file          gd    go to definition
+,rg       ripgrep project          K     hover docs

+jk        exit insert mode         ,?    cheat sheet
 ```
 
-Supported languages: Python, Go, Rust, TypeScript, JavaScript, Shell, HTML,
-CSS/SCSS, JSON, YAML, Markdown, SQL — via `vim-lsp-settings`.

-## Features
-
-### Startup Screen (vim-startify)
-
-Opens when Vim is launched without a file argument. Shows:
-- Session list for current directory
-- Recently opened files
-- Bookmarks
-
-Session auto-saves on quit. Auto-loads `Session.vim` if found in the current
-directory. Auto-changes to git root on file open.
-
-**`vim .` layout** — NERDTree on the left, Startify on the right.
-
-### Keybinding Guide (vim-which-key)
-
-Press `,` and pause for 500ms. A popup lists all available leader bindings
-organized by group. Useful for onboarding and discovering shortcuts.
-
-### Session Management
-
-```vim
-:Obsess              " Start tracking session
-:Obsess!             " Stop tracking
-```
-
-Sessions stored in `~/.vim/sessions/` and automatically resumed by vim-prosession
-on the next Vim launch in the same directory.
-
-### Project-Local Config
-
-Place a `.vimrc` in any project root:
-
-```vim
-" project/.vimrc
-set shiftwidth=2
-let g:ale_python_black_options = '--line-length=100'
-```
-
-Loaded automatically. Security-restricted via `set secure`.
-
-### Large File Handling
-
-Files over 10 MB automatically disable syntax highlighting and undo history
-to prevent Vim from freezing.
-
-### TTY / Console Support
-
-Detected automatically when `$TERM` is `linux` or `screen`. In TTY mode:
-- True color and cursorline disabled
-- Powerline separators replaced with plain ASCII

----
+### Utilities
 
-## Color Scheme
+`,cp` copy full path | `,cf` copy filename | `,ev` edit vimrc | `,sv` reload vimrc | `,wa` save all | `:ChopsticksStatus` diagnostics
 
-Change in `.vimrc` (find the `colorscheme` line):
+</details>
+
+## LSP
 
 ```vim
-colorscheme dracula    " or: gruvbox, solarized, onedark
+:LspInstallServer    " auto-detects filetype
+:LspStatus           " check what's running
+:ChopsticksStatus    " see all tools + LSP + linters at a glance
 ```
 
-True color is enabled automatically when the terminal supports it
-(`$COLORTERM=truecolor`). Falls back to 256-color, then 16-color (TTY).
+pylsp, gopls, rust-analyzer, clangd, sqls — no Node.js. JS/TS servers need Node.
+Markdown LSP (`marksman`) is opt-in so prose buffers stay quiet by default.
 
----
+ALE and vim-lsp coexist cleanly (`ale_disable_lsp=1`). ALE handles linting + formatting. vim-lsp handles everything else.
+
+## Markdown
+
+Markdown opens in writing mode: wrapped text, no spell noise, no concealed
+syntax, no sign column, no real-time markdownlint, and no Marksman diagnostics.
+The explicit commands still work:
+
+```vim
+,mp    " preview in browser
+,mt    " table of contents
+```
+
+Opt into heavier Markdown tooling from your own vimrc before loading
+chopsticks:
+
+```vim
+let g:chopsticks_markdown_lint = 1
+let g:chopsticks_markdown_format_on_save = 1
+let g:chopsticks_markdown_lsp = 1
+let g:chopsticks_markdown_spell = 1
+let g:chopsticks_markdown_conceal = 1
+let g:previm_enable_realtime = 1
+```
+
+For Markdown LSP, install or select `marksman` first.
+
+## Architecture
+
+```
+~/.vim/
+├── .vimrc              thin loader
+├── modules/
+│   ├── env.vim         TTY detection, truecolor, skip built-in plugins
+│   ├── plugins.vim     vim-plug + 24–25 plugins
+│   ├── core.vim        settings, keymaps, performance

+## Performance
+
+| Metric                   | Value                                       |
+| ------------------------ | ------------------------------------------- |
+| Lazy-loaded              | 7 plugins (on command or filetype)          |
+| Built-in plugins skipped | 12 (gzip, tar, zip, vimball, logiPat, etc.) |
+| Large file threshold     | 10MB (auto-disables syntax + undo)          |
+| TTY large file           | 500KB (syntax disabled)                     |
 
 ## Troubleshooting
 
-**Plugins not installed:**
-```vim
-:PlugInstall
-:PlugUpdate
-```
+| Problem             | Fix                                           |
+| ------------------- | --------------------------------------------- |
+| Plugins not loading | `:PlugInstall` then `:PlugUpdate`             |
+| LSP not starting    | `:LspInstallServer` for current filetype      |
+| Colors wrong        | `export COLORTERM=truecolor` in shell rc      |
+| `Ctrl+s` freezes    | `stty -ixon` in shell rc                      |
+| Everything slow     | Large file? Auto-disabled >10MB               |
+| What's installed?   | `:ChopsticksStatus` shows tools, LSP, linters |
 
-**CoC not working:**
-```bash
-node --version   # must be >= 14.14
-```
+More in the [wiki](https://github.com/m1ngsama/chopsticks/wiki).
 
-**Markdown LSP not starting:**
-```bash
-marksman --version   # must be installed separately
-brew install marksman           # macOS
-sudo pacman -S marksman         # Arch
-# or: ./install.sh (installs automatically)
-```
+## Contributing
 
-**vim-lsp server not starting:**
-```vim
-:LspInstallServer          " install server for current filetype
-:LspStatus                 " check server status
-```
-
-**Colors look wrong:**
-```bash
-export TERM=xterm-256color   # add to ~/.bashrc or ~/.zshrc
-```
-
-**ALE not finding linters:**
-```bash
-which flake8 black prettier eslint   # confirm tools are on PATH
-```
