Seven Milliseconds (七毫秒) — Circuit Board (Lemo-Opuscar) · LemoLab × Claude Opus 5.5

No company, brand or logo appears. Converter stations and the hydropower station are named by place only. The boards,
their layout, the charger and every mark are our own drawing in code. Real facts and their sources: FACTS.md.

IMAGES, FOOTAGE, MODELS
- None. Every board (corridor, city, street, charger, loss board) is drawn in code (src/). No photographs, no scans,
  no map dataset (rivers, lakes, coast and city positions are hand-routed from approximate public coordinates),
  no AI-generated images, no 3D models.

LETTERING
- "Routed", the single-line silkscreen font (src/font.js, Latin; src/hanzi.js, the 48 hanzi the boards print, hand-routed
  on a 0/45/90-degree grid): original drawings for this film, not traced from any font.
