assPod: Nano Gen 2 body, chosen on the main menu and kept across launches

- assPod Model on the main menu switches between Video Gen 1 and Nano Gen 2; Color lists the current body's finishes (the nano: silver, green, blue, pink, black, (PRODUCT)RED). The choice is kept in ~/.config/glass-shell/asspod.json beside the glass tune. - The nano: a procedural 2nd-generation model (tools/nano2-model) exported as render models, drawn by podd with anodized aluminum (tinted, bead-blasted, the laser-etched back paler), white end caps and a clickable wheel. Same menus on a 240 x 180 logical screen, so its text is larger, as on the real one; it plays no video. Shown 52.5 mm wide. - podd: one box layout that holds either body, so a switch needs no restart; 64 px between atlas tiles and a 4 px clear band around each eye's image, which removes the hairline rectangle around the body (filtering at the stereo split took the other eye's edge); texture dump and debug modes. - The left stick acts like the right: Steam's d-pad directions are no longer relayed (tilting the left stick down or left pressed the centre button or Menu).

MichaelScottsman	80d4710f3f	assPod: Nano Gen 2 body, chosen on the main menu and kept across launches - assPod Model on the main menu switches between Video Gen 1 and Nano Gen 2; Color lists the current body's finishes (the nano: silver, green, blue, pink, black, (PRODUCT)RED). The choice is kept in ~/.config/glass-shell/asspod.json beside the glass tune. - The nano: a procedural 2nd-generation model (tools/nano2-model) exported as render models, drawn by podd with anodized aluminum (tinted, bead-blasted, the laser-etched back paler), white end caps and a clickable wheel. Same menus on a 240 x 180 logical screen, so its text is larger, as on the real one; it plays no video. Shown 52.5 mm wide. - podd: one box layout that holds either body, so a switch needs no restart; 64 px between atlas tiles and a 4 px clear band around each eye's image, which removes the hairline rectangle around the body (filtering at the stereo split took the other eye's edge); texture dump and debug modes. - The left stick acts like the right: Steam's d-pad directions are no longer relayed (tilting the left stick down or left pressed the centre button or Menu).	2026-10-10 14:08:31 -04:00
