/* ============================================================
   Agent Island — site stylesheet (v6)
   Dark #050507 + teal #20C0B0 system (measured from the logo).
   Orange #E08040 = Claude / alarm surfaces only.
   Gold #E0B050 = micro accents only (logo-center scale).
   Hairline borders, restrained glows, no purple/blue AI slop.
   v4 rule: the product is shown ONLY through real screenshots —
   no CSS-drawn bars, popups, or MacBooks. The v6 hero-bar-shell
   is a HOUSING for the real screenshot, not a redrawn product.
   v6: Raycast-style floating capsule nav, hero bar mid-hero in a
   hardware shell, bigger tilted hero cards with scroll parallax,
   directional reveal choreography, restrained color micro-accents.
   v7 (final): headline periods dropped, hero-meta line and the two
   decorative chips deleted — NO decorative small-print widgets, ever.
   Raycast-grade nav glass (blur 22 / saturate 180, gradient fill,
   inner top highlight), fully symmetric hero cards, and a restrained
   brand-color particle canvas in the hero + final CTA.
   ============================================================ */
