# Hallmark Design System (Pinned MIT Adapter)

1. Define OKLCH color tokens on `:root` (`--bg`, `--surface`, `--ink`, `--muted`, `--line`, `--accent`) and set `overflow-x: clip`.
2. Use a strict 4px spacing rhythm (`4, 8, 12, 16, 24, 32, 48, 64px`), `text-wrap: balance` on headings, and sentence-case labels.
3. Prefer hairline rules and borderless register tables over nested cards, pill-badge confetti, or 4-card stat rows.
4. Remove uppercase eyebrow kickers above headings, decorative arrows glued to link text, em-dashes, and middle-dot walls.
5. Verify every rendered HTML surface with `sloplint.mjs` (`0 FAIL` required before release).
