   mk.css — Matthew Karsten layer on top of the jdm-site / lct-site

   Palette from psm-brand/assets/palette.json: purple #A855F7 (fill),
   #7e22ce (text + buttons, 7:1 behind white), deep violet #2d1b4e,
   near-black #160d26, gold #FBBF24 (accent only, dark text on it),

   The contrast rule INVERTS, exactly like jdm-site's pink:
     --sol     #14F195  FILL + text on DARK only (10-13:1 on the violet grounds,
                        but 1.3-1.5:1 on any light ground: never text on light)

                        on white; 2.9-3.7:1 on dark, so never on dark)
   Both directions are pinned by tools/audit.py (pairs + a selector guard).
   --grad-sol matches the accent on karsten.cv/solana; it only ever draws
   hairlines and underlines, never a field. */
