…ation Removing the builder's lazy boundary put the command bar in the server HTML, so Playwright clicked option cards before React attached handlers. The root component now marks the document once hydrated and the e2e navigation helper waits for that mark. Updating the performance baseline now rejects an existing pre-migration baseline instead of silently rewriting it as version 2.

Problem
Landing pages download builder catalogs and content loaders they do not use. The homepage also hides its headline until hydration and animation finish. In the builder, typing a project name rerenders option cards and runs a second render to update the generated command, while secondary panels and the Run bundle load before they are needed.
Solution
Compute marketing display data from the canonical catalogs at build time, and keep content loaders and stack parsers behind their route boundaries. Render the hero immediately, lazy-load technology images, and serve the preloaded Geist fonts as hashed assets. Decorative animation pauses offscreen, in hidden tabs, and for reduced-motion users.
The builder now derives its command during rendering, memoizes compatibility analysis and option cards, and indexes capability evidence once per inventory update. Presets, saved stacks, import and share dialogs load on demand. Run warms on pointer or keyboard intent. Removing the nested builder lazy boundary lets its content render with the route and avoids another loading waterfall.
The performance guard now follows the Vite manifest's real entry and static dependencies. Its previous filename heuristic measured a 258-byte chunk. The entry baseline is migrated from a production build of main at
8ea3b9b70; the other budgets retain their existing limits.Evidence
Compared with that main build, gzip JavaScript preloaded by the homepage falls from 516,751 to 315,412 bytes, a 39% reduction. The MCP and Run-before-clone landing pages fall by 36% and 38%. The homepage's rendered text is unchanged.
In three alternating browser runs per build, median project-name typing latency falls from 264 ms to 96 ms across 15 interactions per build. These are local production builds replayed through Chromium at a 390 × 844 viewport with 4× CPU throttling, not deployed network or field measurements. JavaScript fetched during the builder flow falls from 685,476 to 519,255 gzip bytes, and Run is no longer fetched on startup. The builder now preloads more of its route because it renders immediately, so its HTML preload total alone is not a like-for-like startup comparison.
Solo selections, command text, URL state and clipboard output agree after edits. Multi-mode selections survive reload, deferred panels open, and docs navigation and German rendering work.
Scope
This PR contains the website performance changes on current main. The separate composer, CLI, generator and content work remains outside this branch.
The browser template-generator bundle already exceeds its existing size budget on main: 773,928 gzip bytes before and 773,949 after. Its source is unchanged, and this PR does not widen that budget. Further generator splitting remains separate work.
