fkwpandClaude Opus 5.5 3d57920556 Offer background effects as a grid in the camera menu
- The camera menu's blur toggle becomes a Background effects section
  under the cameras: no effect, blur and the two shipped backgrounds as
  one radio choice of tiles, three across. It scrolls with the device
  list, so it stays reachable in a short call, and choosing keeps the
  menu open. The lobby gets it too, as both render the same footer.
- The footer's view model gives the options, the notice and the actions;
  the footer only names them.
- Each tile is Compound's MenuItem as a menuitemradio, styled as a tile.
  Compound makes it an item of the dropdown, so the arrow keys walk the
  tiles with the device rows, and takes its tap in the phone drawer. A
  tile that can't be chosen has no select handler, so the keyboard passes
  over it.
- Where the browser can't run effects the tiles are shown, disabled and
  explained by a notice the group is described by. No effect stays
  choosable and shows as in force. The notice is in the scrolling list,
  so a short call doesn't push the menu out of it.
- Section headings are raised, or the positioned tiles scroll over the
  one they sit under; raised within the list only, so the menu's frame
  stays over them. Tiles clip with overflow: clip; with hidden they are
  scroll containers, which focus scrolls into view without their border.
- End to end on Chromium and Firefox: a shipped background chosen in the
  lobby shows in the preview, and None after Blur draws nothing, counted
  in WebGL draws (Blur: about 1400 a second on Chromium, 2300 on
  Firefox).
- The Quick Audio Menu's test of the camera menu keeps its name and now
  finds blur among the effects rather than as a toggle.
