- ☑ `refrakt contracts` / `structures.json` enumerate per-variant structures.
- ☑ CSS-coverage tests cover per-variant selectors.
- ☑ `refrakt inspect <rune> --<modifier>=<value>` renders the corresponding variant (no new flag needed).

refrakt contracts / structures.json enumerate per-variant structures.
CSS-coverage tests cover per-variant selectors.
refrakt inspect <rune> --<modifier>=<value> renders the corresponding variant (no new flag needed).

inspect already takes attributes, so variant selection rides them. SPEC-091 Implications.

Completed: 2026-06-09

Branch: claude/spec-091-engine-variants

packages/transform/src/contracts.ts: each rune with variants enumerates a per-variant RuneContract (base merged with the delta) under variants[axis][value].
packages/lumina/test/css-coverage.test.ts: expectedSelectors folds in selectors introduced by variant deltas.
Confirmed refrakt inspect <rune> --<modifier>=<value> selects a variant via the existing flag→attribute path (no new flag).
