ClintchizandClaude Opus 5 361129b6ac perf(build): budget the runtime on what ships, not on source bytes
The runtime budgets measured raw source, which counts comments -- and the
production build minifies, so comments cost a visitor nothing. The metric
therefore rewarded deleting explanatory comments over writing smaller code,
and could not tell a real feature from a wall of prose.

They now measure the minified output, which is what is actually served:
/__wrnexus/reactive.js is its own file, minified, with an immutable year-long
cache. The reactive runtime is 69684 minified against a 80000 budget, from
175246 raw -- roughly 21kB gzipped, fetched once.

Also fixes two real bugs found while testing the showcase:

  - object-valued props were serialised as a bare {...} attribute, which the
    compiler read as interpolation and tried to parse as JavaScript. That
    returned 500 for /components/navbar. Arrays start with [ and were never
    affected, which is why only object props broke. All 108 pages now render.

  - the runtime walked text nodes inside textarea, script and style, so a
    JSON sample in a textarea was evaluated away.

Navbar styles move out of ui.css into the component, matching the rest of the
navigation group. No declarations changed: 4519 before and after.
