Form / not fixed.

• The opening uses the original prototype CAD renders from SMR2. SMR4 adds depth-tested light masking and an 18-second connected sequence. It is now labelled first prototype rather than a finished V1 product.
• Concepts change the board outline and component positions. The controller, button and most passives are now on the front face. Copper and silkscreen artwork is illustrative, not electrically routed. They reuse the original controller, balance connector, one original button and the original passive components. These are visual form studies; electrical routing and manufacturability are not established.
• T65 family: TCWIN C48982518, identified by the user’s JLCPCB link and reference photograph. The 3D package is a photo-based envelope with assumed 2.0 × 1.7 × 0.85 mm body orientation, not manufacturer MCAD.
• 21 LEDs means 11 front + 10 back; 28 LEDs means 14 + 14. These are concept counts, not an asserted drop-in PCB or firmware release.
• CAD-rendered visibility masks suppress hidden LEDs and remove foreground-component silhouettes from the light layer. Glitches slice the rendered board, split colour channels and add masked digital fragments. Whole rendered contours and component placements also change. Text and background remain stable.
• No AI image/video generation. CAD rendering, motion graphics, code and wording were produced with substantial OpenAI Codex assistance under Nikos’ direction.
