/* ============================================================
   gatekeyp — Web UI design system
   Monochrome editorial minimalism (Phase 3.5, 2026-08): pure
   ink, one grayscale ramp, texture instead of color. Status is
   carried by shape, hatching, weight and glyphs — never hue
   alone. Webfonts are self-hosted (ABC Areal, no CDN, no trackers)
   so the UI stays as privacy-lean as the product. Single dark
   theme (2026-09-08): black paper, white ink; the light theme and
   its toggle were removed.
