/* Has AI Heard of You? — warm, light, flat "calm report card" theme (loop 2).
   Owner reference: outbid.lol's calm/soothing visual recipe, adapted to our
   brand — warm near-white background, warm near-black ink, ONE warm
   terracotta accent used sparingly, flat cards (no box-shadow) with
   accent-tinted backgrounds/borders instead of shadow depth, full-pill
   buttons, large border-radius. Colors painted explicitly (one committed
   look, no dark remnants, no prefers-color-scheme dual theme).

   Font: Build #1c (2026-08-26) — owner granted explicit permission to
   download DM Sans; self-hosted, latin-subset, variable-weight woff2
   (fonts/dmsans-variable-latin.woff2, 62,724 bytes), preloaded from both
   HTML pages. Loop 2 shipped a system-stack fallback only because no live
   user was available to grant the download permission at the time — this
   supersedes that deviation. */
