/* ==========================================================================
   KIT: the shared look (claudia.gallery). Loaded LAST by _includes/head.html,
   after main.css, merch.css, cart.css, sponsor.css, newsletter.css and core.css,
   so one definition covers every component without editing each file.

   Rules of the look
   - Square corners, 1px hairlines, no glow shadows, no gradient fills.
   - Mono uppercase labels (letter-spacing .14em), condensed uppercase titles.
   - Clay (#d97757) is the one accent. Text on clay is near black.
   - Cards sit on --bg2, hairline --line2, hover brightens the border only.
   Tokens (--bg, --ink, --clay ...) are declared in main.css.
