Markdown layout controls occupied a permanent bordered popup over the document.
- Move them into the editor tab strip with layout icons. When tabs are hidden, including Distraction Free Mode, show one floating toolbar that appears on mouse activity and fades after inactivity.
- Use the same floating toolbar for the HTML browser controls.
- Keep keyboard access: hold the toolbar while focused, return focus on Escape, and respect reduced motion. Add theme tokens with their import, template and reference entries.
* feat(vcs): IDEA's diff algorithm and change colouring in the diff viewer
Port IntelliJ's text comparison to TypeScript (src/features/vcs/comparison):
Myers/patience LCS with unique-element discarding, ByLine (smart matching
that skips unimportant lines, chunk optimizer, second-step correction),
ByWord (word chunks, punctuation matching, whitespace policies, line block
splitting) and ComparisonManager's compareLinesInner / processBlocks. The
port runs IntelliJ's own LineComparisonUtilTest, WordComparisonUtilTest and
SplitComparisonUtilTest cases (459 runs), converted to ideaCases.json.
MergeView chunks now come straight from these line fragments, with the
inner word fragments as chunk changes, instead of @codemirror/merge's
presentable diff. Revert and >> / << replace lines as
DiffUtil.applyModification does.
Colour changes as IDEA does: modified (blue), inserted (green) and deleted
(grey) by chunk type, a lighter line background for chunks whose words were
compared, each word fragment in its own type at full line height, a thin
bar for a fragment empty on one side, and the colours carried into the
gutters and the divider bands. New --diff-modified / --diff-inserted /
--diff-deleted theme tokens, imported from .icls DIFF_* attributes.
Add a Playwright suite over a generated git repository of diff cases,
including 10,000-line files, in every viewer mode.

Two editor toggles under Settings › Editor › Color Scheme › Language Defaults (off by default, also actions `editor.toggleRainbowBrackets` / `editor.toggleSemanticHighlighting`):
- Semantic highlighting (IDEA's rainbow variables): locals and parameters coloured by a name hash from LSP semantic tokens; fields, statics, constants, library symbols untouched.
- Rainbow brackets (VS Code's bracket pair colorization): (), [], {} by depth, unmatched in the error colour, strings/comments skipped, visible ranges only with 4 KB checkpoints.
Palettes are theme tokens (`--syn-rainbow-1..5`, `--syn-bracket-1..3`, light/dark/high-contrast), editable in the Color Scheme tree, and mapped from IntelliJ `.icls` RAINBOW_COLOR1..5.
App verification on macOS found the colours were overridden by the syntax highlighter's span nested inside the marks; the rules now cover descendants. Verified both toggles on/off live in a TS file.
Fixes#56https://claude.ai/code/session_01VUYsdXA2nkF5v6zsC93dpn
Per the maintainer's decision for #24, no third-party themes are bundled; instead a theme plugin template and docs let the community port themes (IntelliJ also ships few themes, the rest are plugins).
- templates/theme-plugin: manifest-only plugin with an original example (Harbor Night) covering every UI token and an editor scheme (.icls equivalent).
- docs/plugins/themes.md: format, IntelliJ / VS Code porting tables, generated token reference (pnpm gen:theme-docs); drift test fails when tokens.css and the template/reference disagree.
- pnpm theme:import-intellij: dependency-free converter for IntelliJ .theme.json (+ .icls).
- Plugin host: themes may name an editor-scheme merged over the theme; comments allowed in theme files.
- Fixes: a plugin theme's kind now switches the light/dark base; plugin themes go in their own stylesheet so the Appearance accent and editor scheme still layer on top.
Verified: ide-plugin tests, vitest (44), in-app on macOS: installed the template from disk, applied Harbor Night (dark base + teal accent over Islands Light), back to default restored the light theme.
