/*
 * overlays.css — visual styling for the overlay system (Sprint 2 Phase 6).
 *
 * Covers everything the overlay JS emits:
 *   - GtexTissuePanel.render() output (.gtex-tissue-panel and children)
 *   - <source-chip> custom element
 *   - NotForClinicalUseBanner auto-mounted node
 *   - ProvenanceStore.renderCitationModal() output
 *
 * Loaded by web/app/index.html AFTER style.css so overlay selectors take
 * precedence on the rare class overlap. The palette mirrors chromly's
 * existing dark theme: slate-900 backgrounds, violet accents, slate-200
 * text. Color contrast targets WCAG AA on the slate-900 background.
 *
 * Sprint 2 Phase 6 — Phase 4/5 emit the DOM; this file styles it.
