Max Litruv Boonzaayer e058165830 feat: upgrade toolchain and soften sync recovery after network blips

Bump Vite 8, matrix-js-sdk, and related deps; fix immer/vanilla-extract imports for new majors. Replace blocking sync error dialog with background recovery on wake/offline, and disable Vite auto-open in dev. Add feature handoff documentation index.

Message rendering — handoff

Summary

Built-in plugins parse and render message bodies: custom markdown (block + inline), HTML sanitization, syntax highlighting, matrix.to links, emoji shortcodes, bad-word filter hooks, and PDF preview support.

User-facing behavior

Messages render formatted text, code blocks with Prism highlighting
Clickable matrix.to / room links
Custom emoji from packs inline
Spoiler/highlight/color extensions where enabled

Architecture

RenderMessageContent.tsx
  → react-custom-html-parser.tsx
  → plugins/markdown/ (block + inline parsers)
  → plugins/react-prism/ReactPrism.tsx
  → plugins/emoji.ts, matrix-to.ts, color.ts
msgContent.ts — content type detection

Key files

Path	Role
`cinny/src/app/components/RenderMessageContent.tsx`	Main render entry
`cinny/src/app/plugins/react-custom-html-parser.tsx`	HTML → React
`cinny/src/app/plugins/markdown/`	Markdown rules + parsers
`cinny/src/app/plugins/react-prism/ReactPrism.tsx`	Code highlighting
`cinny/src/app/plugins/emoji.ts`	Emoji shortcodes
`cinny/src/app/plugins/matrix-to.ts`	matrix.to link handling
`cinny/src/app/plugins/bad-words.ts`	Content filter hook
`cinny/src/app/plugins/color.ts`	Text color
`cinny/src/app/utils/sanitize.ts`	HTML sanitization
`cinny/src/app/features/room/msgContent.ts`	Message content helpers

Data model

None — pure functions over message content JSON.

Dependencies

prismjs (via react-prism)
pdfjs-dist wrapper for PDF thumbnails
millify for number formatting in embeds

Integration points

room-timeline: all message bodies
forum: forumRichText.ts, ForumMessageBody.tsx
custom-emoji-packs: emoji plugin reads pack data
embed-filters: separate from body render — URL preview gating

Testing

Manual

Send markdown: bold, code fence, link.
Verify matrix.to link navigates in-app.
Custom emoji shortcode renders image.
XSS attempt in message — should sanitize.

Automated

None

Known issues & gotchas

Markdown rules split block vs inline — order matters in parser
bad-words.ts may be no-op depending on config
HTML from other clients may not match Paarrot markdown subset

Future work

CommonMark test suite
Lazy-load Prism languages
