/* Loveland HCR — app-wide professional polish layer (Stage 3).
 *
 * ADDITIVE by design. Loads AFTER styles.css but uses only LOW-SPECIFICITY,
 * element-level selectors, so component rules (.bv-*) always win — this layer
 * fills gaps and adds consistent interaction feel WITHOUT overriding layout or
 * structure. Keys entirely off the existing design tokens (tokens.css), so it
 * respects light / dark / high-contrast themes and reduced-motion automatically.
 * Fully reversible: remove the <link> in index.html (and from the SW precache).
