satori + @resvg/resvg-js, cached on disk by slug + updatedAt. Bundles
Brygada 1918 + Commit Mono fonts as server assets, ships a fallback
default.png, and patches @shuding/opentype.js via patch-package.

private/auth/admin pages.
Replace ghost/whisper/sparkle color palettes with guild/candlelight/parchment/ember/earth tokens.

layouts, and pages to new design system. Add circle color tokens, typography scale, prose-guild
class, and warm texture effects. Clean up stale documentation files.
