/* The Adventures of Happyweed! — site chrome. Desktop-only by design.
   Theme: weed greens, with accents strobing through the AUTHENTIC in-game
   super-drug flash cycle — CLUT slot 140 across phase palettes 128..132
   (assets/super_drug/famcap/clut_F128..132.txt): lime, pink, green, white,
   purple. Hard steps, like the real palette flash — never a fade.
   The hero keeps the game's main-menu blue (0,0,255) so the original PICT
   art blends seamlessly. */
