/* BulkMaker v2 — design system
   Direction: clean technical/editorial light theme. White background, near-black ink,
   one confident accent (indigo), thin 1px borders instead of shadows, monospace for
   brand mark/labels/code. No dot-grid texture, no emoji-bento cards — flat bordered
   cards with tag-style labels instead. Distinct from both the dark v2 and the
   original KeySynth look. */
