   VYROX Quarry - site stylesheet (aikuari.com)
   Day theme only (owner brief). Three token layers: primitive -> semantic ->
   component. Shape rule: interactive controls are full pills, media tiles are
   20px, inputs 12px. One accent: VYROX blue. System font stack (SF Pro on Apple).
   No sticky or fixed chrome anywhere: the header scrolls away with the page.
