/* ===========================================
   Base element styling
   Replaces the typography / link / button / table base that PicoCSS
   used to provide. modern-normalize handles the low-level reset
   (box-sizing, margins, form font inheritance); this layer applies the
   Collony design language (Geist, role tokens, weight 400 headings).
   Token-only — no hardcoded colors.
