/* Shared stylesheet for the standalone legal pages (/privacy, /terms).
   Mirrors the Glass Flow landing design system: slate-50/950 canvas, twin
   radial hero glows, glass sticky header, Sora display + Inter body (the same
   self-hosted woff2, copied to /fonts for these unbundled pages), blue icon
   chips like the old LegalModal. Dark mode is CLASS-driven (html.dark), set by
   /theme.js from the SAME localStorage.theme the in-app toggle writes — dark by
   default, exactly like the app shell. No prefers-color-scheme fallback here:
   the app ignores the OS setting, so a media query would fight a stored choice
   (stored 'light' + OS dark would wrongly render dark). */
