   bgbgone.franzai.com — MOBILE-FIRST, FLUID stylesheet
   --------------------------------------------------------------------------
   KISS + DRY. Base rules target the phone; desktop is the exception, layered
   on with `min-width` media queries only. Type and spacing are fluid
   (clamp), and card grids use auto-fit, so most breakpoints disappear.
   Single source of truth: every colour/alpha lives on :root — no hex/rgb
   anywhere else. System fonts only. No framework, no CDN.
