feat(landing): pixel design ported to static Astro + en/es/eu i18n

Adopt the "Carved from stone" pixel design (landing/design/) as the apex
onboarding page, ported from its React/Babel-via-CDN prototype to static
Astro so it works on an offline LAN. Real modded-LAN content replaces the
prototype's fictional public-SMP copy.

- Vendor web fonts locally (tooling/fetch-fonts.sh -> public/fonts/) so the
  page renders without the Google Fonts CDN at party time.
- Port the design system (main.css: mood/hero/bevels) and split markup into
  Astro components (Creeper, PixelIcon, CopyChip, ServerListPanel).
- site.ts holds language-neutral config + theme knobs (mood/hero/headFont/
  dust) that replace the design's in-browser TweaksPanel; LITERALS holds
  never-translated product/in-game terms.
- i18n: English (/), Spanish (/es/), Euskera (/eu/) generated from one
  [...lang].astro via getStaticPaths; copy lives in src/i18n/ui.ts. Nav has
  an EN/ES/EU switcher; html lang + hreflang set per page.
- Status panel shows a static server-list row + honest stat tiles (no fake
  live count). Copy + scroll-reveal are the only client JS.

Build emits to ../www (gitignored). Euskera strings pending a native review.
