Simplify the Circular Arcades talk to 27 minutes and three demos

[alecu]

The previous talk assumed a coding audience throughout and had eleven launch stages. Replace it with a 12-minute public introduction and a 15-minute coding section, reduced from 33 slides to 21.

The introduction covers Cybercirujas with the supplied photo, Ventilastation’s moving radial display and arxels, transformed artwork, existing alecu and community games, two controllers and audio, and scenes and visual drawables. Invite the audience to the official October 14 itch.io jam, with games intended for The Overkill on November 26–29.

The coding section focuses on angle/depth, wrap-aware collisions, reserving the display graph, indexed art, draw order and readable HUD text. Keep exactly three cumulative launch buttons: steering, catching/planting, and the completed shared cloud garden. Preserve the completed game and SDK pin. Update speaker pacing, reading view, presenter guide and presentation checks.

Add WebGL captures of six existing games, the radial cell-size example, the title and the planting stage. Capture records and scripts make the images reproducible. All game/display images retain WebGL glow.

Validation: Jekyll and warning-free Sphinx builds, all seven website content tests, presentation/source/archive checks, exactly three launch stages, and visual inspection of all 21 rendered slides passed. Chromium reported no page errors or content overflow.
