/* VeLens — Button System (mc-btn)
 * ──────────────────────────────────────────────────────────────────
 * Single button system used across every UI surface. Replaces 60+
 * one-off button classes (.mo-close-btn, .errlog-filter-btn,
 * .palette-sort-btn, etc.) with a small variant matrix:
 *
 *   .mc-btn             → base (interactive defaults)
 *   .mc-btn--primary    → filled blue CTA
 *   .mc-btn--secondary  → outlined neutral
 *   .mc-btn--ghost      → transparent, hover-tinted (icon header buttons)
 *   .mc-btn--danger     → filled red, irreversible action
 *   .mc-btn--pill       → rounded pill (filter / range tabs)
 *   .mc-btn--icon       → square icon button (close, refresh, settings)
 *   .mc-btn--sm         → smaller variant (refresh, compact pills)
 *   .mc-btn--lg         → larger variant
 *   .mc-btn--block      → full-width
 *
 * MIGRATION
 *   Bespoke classes (.mo-close-btn, .mo-range-btn, etc.) stay on the
 *   element as behavior tags so existing JS querySelectors keep working.
 *   The visual styling lives here; bespoke CSS rules can be stripped
 *   one surface at a time as the migration progresses.
 *
 * INJECTION
 *   Same pipeline as tokens.css — prepended to every Shadow DOM stylesheet
 *   in content/content.js loadCSS chokepoint, and linked into popup.html.
