 ### Breaking Changes
 - **tokens:** removed the fixed `--sf-animation-delay-1…5` stagger tokens, superseded by the new `.sf-stagger` utility + `--sf-stagger-step` knob. Replace `style="animation-delay: var(--sf-animation-delay-N)"` on hand-indexed children with a single `.sf-stagger` class on their parent (see `docs/motion.md`); to keep a fixed manual delay, use a literal (e.g. `animation-delay: 150ms`).
+- **macros:** removed `.sf-corner-scoop` (and its `--top-left`/`--top-right`/`--bottom-left`/`--bottom-right` modifiers and `--sf-corner-scoop-size`/`--sf-corner-scoop-at` knobs). Judged too niche for the public API relative to its cost — the single absolute cut size needed per-element tuning across control- vs hero-sized boxes, and the mask clipped `box-shadow`/`border` and could not compose with the other mask-based macros. To keep a concave corner, apply the mask directly on the element: `style="-webkit-mask-image: radial-gradient(circle at 100% 0, transparent 24px, black 24.5px); mask-image: radial-gradient(circle at 100% 0, transparent 24px, black 24.5px)"`.
 - **layout:** renamed `.sf-bento--compact` / `.sf-bento--tall` (container row-height modifiers) to `.sf-bento--row-compact` / `.sf-bento--row-tall`, matching the `--sf-bento-row-*` tokens they set. The old names collided visually with the unrelated child modifier `.sf-bento-tall` (spans one item over 2 rows) — same word, one dash apart. Child span classes (`.sf-bento-wide/-full/-tall/-featured`) are unchanged. See `docs/migration.md`.
