/* Menu and Button Enhancements */
/* ===== Button hover ====================================================
   MudBlazor 8 emits a single combined class per filled button —
   .mud-button-filled-{color} — NOT .mud-button-filled.mud-button-{color}.
   The old per-colour rules used the latter and never matched (dead rules);
   buttons fell through to MudBlazor's native :hover, which paints
   var(--mud-palette-{color}-darken). Those *-darken vars are undefined under
   our custom palettes, so the hover background resolved to transparent and
   read as BLACK over the page. Filled icon buttons carry the same
   .mud-button-filled-{color} class, so the colour-mix rules below cover them
   too. Outlined/text hovers are handled further down. ==================== */

/* Icon button hover — shade the rendered colour via filter (brighten in dark,
   deepen in light). This works for ANY icon button (plain, or filled/coloured)
   and can never force it to a flat grey/transparent. MudBlazor's own subtle
   overlay still gives plain icon buttons their neutral hover feedback. */

/* Filled buttons — re-assert the base palette colour on hover (so MudBlazor's
   native :hover, which paints the undefined *-darken vars, can't take over) and
   shade it in-family with filter. No color-mix, so it resolves in every browser. */

   it avoids the stale-variant bug where a component that reads
   ThemeService.IsDarkMode keeps the old image/colour until it happens to
   re-render. Dark is the default (shown when no data-theme is set). */
