/* Cison — landing + auth (public) surfaces · s/public_v100.css  (Phase 5.7)
   ─────────────────────────────────────────────────────────────────────────
   Loaded ONLY by the lean `public` skeleton (no app chrome, no jQuery, no
   Font Awesome), AFTER global_v100.css — so it reads the brand tokens defined
   there (--ruby/--ink/--font-sans/--font-mono/jewels …) and owns the full-page
   layout for the logged-out landing / sign-up / invite surfaces. The in-app
   component layer (components_v100.css) is NOT present here.

   Visual language is the locked Journey (invite/s/preview_v100.css): dark hero
   on the near-black substrate, jewel-tone glow, Geist sans + Geist Mono
   eyebrows, generous type — but simpler (single-screen, one card). Sign-up /
   invite forms sit on a calm cream surface in a white card.

   Font-size floor (project rule + font_floor audit): nothing below 0.875rem
   except mono/eyebrow/label/footnote classes, which may sit at 0.75rem. Always
   rem, never px for font-size. */
