Add CSS editor banner and update Avalon member count

- Bump Avalon member count to 885 - Add looping, muted video banner linking to the new Janitor profile CSS editor - Desktop: show the Avalon and CSS banners side by side - Mobile: show them in a carousel (random start, 8s auto-advance, arrows/dots) - Paint video frames to a canvas so browsers like Opera GX don't overlay pop-out controls on the banner Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
