Compact feed header on phones so more Pokémon are visible

- Filter chips + sort + type/gen/random collapse behind a 'Filters & sort'
  toggle on < 900px (always shown on desktop); toggle carries a badge with
  the active-filter count; open state persists
- Smaller title / progress ring / search on < 560px
- Shorter dex cards on phones (tighter padding, 94px sprite): ~209px vs
  ~250px, so ~4-5 Pokémon fit above the fold instead of ~2-3
