/* Alena TV-lite — TV / weak-browser stylesheet.
   Rules:
   - no :hover (TVs have no pointer)
   - focus state must be high-contrast and obvious from across a room
   - px units only (no rem/vw/clamp — they break on old WebKit)
   - flex only (no grid, no gap-on-flex — older Tizen/WebOS lack support)
   - one accent color: #FF7043 (Material Deep Orange 400) */
