/* ============================================================================
   SYNTHWAVE CHROME — "Neko's Knowledge Vault"
   One disciplined synthwave system over the whole app.

   The laws:
   1. Two accents, two jobs. CYAN is the machine — every border, link and
      structure line. MAGENTA is the cat — the brand and whatever is selected.
      The sun keeps its yellow-orange-pink gradient, but only inside the sun
      (the header diorama and the site-home hero, which is the same scenery).
   2. Glow is feedback, not decoration. Nothing glows at rest except the neon
      signs: the wordmark, the sun, the active nav pill. Hover/focus/active
      earn their glow.
   3. Type: Bungee is the signage display (motto + standalone page titles),
      Audiowide is the quiet kicker voice, Mr Dafoe is the motel-sign script
      (the wordmark), Oswald is the condensed HUD voice (labels, nav,
      buttons, numbers), Rajdhani is everything humans read.
   4. The scenery is a dusk poster, not an arcade: pine ridges and the banded
      sun (no perspective grid) under a violet-to-indigo sky.

   Note *prose* keeps the Obsidian typography for readability; this sheet only
   skins the chrome around it. Loaded after obsidian-theme and blog-adapter so
   it wins the cascade.
