Tracker: kit/ frontend toolchain modernization (Svelte 5 / SvelteKit 2 / Vite 7 / Tailwind 4 / ESLint 10)

[mishig25]

Tracker for the kit/ frontend modernization series. All work is done — kept for reference.

• Upgrade kit/ to Svelte 5, SvelteKit 2, Vite 7, Tailwind 4, ESLint 10 #792 — Svelte 5 / SvelteKit 2 / Vite 7 / Tailwind 4 / ESLint 10; svelteKitCustomClient fork replaced by reroute hook + click listener
  • Fix Svelte 5 compile break on raw-HTML tables (<table><tr> without <tbody>) #793 — <table><tr> repair for Svelte 5's node_invalid_placement (unbroke hub-docs; preempted diffusers/trl)
  • Keep shorthand doc URLs in the address bar on client-side navigation #794 — Shorthand doc URLs preserved in the address bar on client-side navigation
• Migrate kit/ components to Svelte 5 runes (fixes broken docstring tooltips) #795 — Runes syntax across all components + docstring tooltip fix

Possible future follow-ups (not tracked here): migrate the last 3 named-slot components (FrameworkContent, InferenceApi, TokenizersLanguageContent) + their preprocessors from slots to snippets (requires runes-mode generated pages, i.e. let fw = $state(...) in convert_md_to_mdx.py, and course-repo e2e testing), and emit <script module> instead of the deprecated <script context="module"> in the mdsvex generator.

Verified locally (full accelerate + hub-docs builds compared against pre-upgrade baselines, plus browser tests for hydration, client-side navigation, shorthand URLs, and docstring tooltips), and the production docs are now built and live with the new toolchain:
