/* I'm AiDog — aidog.im v1 static site, "fresh water" white skin.
   Palette extracted from the product logo (tmp/aidog.jpg):
   warm white #fcfcfa (canvas), deep navy #001633 (wordmark / outlines),
   tech blue #2892ff (collar — primary action), mid blue #1c519a,
   glow cyan #70e4fd (halo light — droplets and glows), mist #d4eaf1,
   blue-gray #a5b7ca (fur shadow — hairlines),
   coral #e98667 (inner ear — warm accent, sparing).
   Droplet motif: teardrop dots (rounded-square rotated 45deg) plus the
   falling-drop canvas in the hero.
   Zero dependencies: system fonts only, no CDN. */
