/* ============================================================
   DevAdy — Landing (Cozy modern + pixel-art sprinkles).
   Landing-only design exception via local --r-* tokens so
   brand.css remains canonical for admin and printable invoices.
   Same scope-exception pattern as the "paper on dark" invoice.

   Aesthetic: modern dark UI on a cozy navy palette pulled from
   the night-coding GIF, with retro flavor used as accents only:
   - Pixel-art GIF as the hero centerpiece
   - Tiny Silkscreen/Press Start 2P labels (eyebrows, chips, step
     numbers) as retro sprinkles
   - Soft modern shadow stacked with a 3px solid pixel-offset for
     a subtle "card on a card" toy feel
   - VT323 retained for the terminal block (it earned its keep)
   - Headings + body return to Space Grotesk / Inter
   ============================================================ */
