/*
 * psychprofile shared test shell.
 *
 * Structural primitives shared by every test under public/tests/<slug>/.
 * Link this BEFORE the per-test style.css so the test file can override
 * tokens (colours, gradients) while inheriting layout.
 *
 * Per-test style.css is responsible for:
 *   - palette tokens (override :root --test-* variables)
 *   - hero gradient + hero shapes
 *   - primary CTA button gradient (.btn-hero)
 *   - section background blobs
 *   - card pastel rotations (:nth-child)
 *   - heading gradient
 *
 * Everything else lives here.
