/* amadan — Ink & Verdigris.
   Direction contract (docs/superpowers/specs/2026-08-08-amadan-web-ux-design.md;
   lives here because html/template strips HTML comments, and this file
   ships verbatim in the binary at /static/css/amadan.css):

   THESIS: GitHub's grammar with amadan's heart. The one rule — "if the
   server is compromised, the attacker gets nothing" — is the hero,
   verbatim. Refused: the anonymous GitHub clone; dark-hacker neon.
   OWN-WORLD: Irish scriptorium rendered modern. Iron-gall ink neutrals
   (warm green cast, never GitHub blue-gray), verdigris accent, red-lead
   danger, gilt amber private tier. System-stack type throughout (speed
   embodied; Paul cut the display webfont 2026-08-08 — "horrible"),
   Commit Mono for code. Filled verdigris sealed chip for E2EE; outline
   chips for public/private. Wide field: 1400px cap, 60rem reading
   pages (Paul: wider, 2026-08-08).
   STORY: a developer recognizes GitHub instantly, reads plainly what
   amadan can and cannot see, and feels pages land instantly.
   FIRST VIEWPORT: signed-out home = the one rule set huge, one line of
   what amadan is, sign-in CTA, three-tier honesty ledger as the demo.
   FORM: brief-pinned direction (GitHub-familiar + amadan twist); no
   seed roll — user-pinned beats the roll.
   FINISH: unreviewed and undocumented is unfinished; this build ends
   with the finish review, the verdict, and DESIGN.md.

   No external requests: fonts below are embedded in the binary and
   served same-origin under CSP default-src 'self'.
   🤖 rewritten in the web-UX pass, 2026-08-08 (previous look: Task 5,
   2026-08-03). */
