   MacroPad PWA — "Tactile Deck"
   A macro deck that reads like a slab of physical keys: warm near-black
   surfaces, an electric-violet signature accent, softly-raised cards with a
   hairline top highlight, and a satisfying pressed state.
   Self-contained (no external fonts/CDNs — CSP forbids them).
