/* =============================================================
   onlinemorsecode.com — Character pages stylesheet
   IMPROVED VERSION (v2)

   Changes vs v1:
   - Hover dim moved off ALL links — only decorative ones now dim.
     Inline content links inside .lp-p get an underline + safer hover.
   - Hover-to-open dropdowns scoped to (hover: hover) so touch
     devices get click-to-open without conflicts.
   - Reduced-motion media query no longer flattens essential
     blink-light transitions.
   - WCAG: brighter accent on hover for muted-text links to keep
     contrast over var(--bg).
