How Far Can You See? (你能看多遠？) — Marker on Paper (Lemo-Opuscar) · LemoLab × Claude Opus 5.5

IMAGES, FOOTAGE, MODELS
- None. Paper, every stroke, the figure, ship, tower and plane, the peel and the subtitle slip are drawn in code
  (pen.js, film.js). No photographs, no scans, no AI-generated images, no 3D models.

FONTS (SIL Open Font License 1.1; licence texts in fonts/; the .ttf files are not in git, build.sh downloads them)
- Kalam Bold / Regular — Indian Type Foundry — https://github.com/google/fonts/tree/main/ofl/kalam (fonts/Kalam-OFL.txt)
- LXGW Marker Gothic 霞鶩漫黑 — LXGW — https://github.com/google/fonts/tree/main/ofl/lxgwmarkergothic
  (fonts/LXGWMarkerGothic-OFL.txt); subset by tools/subset_film.py to the characters in tools/zh_chars.txt.
- Handwriting order: glyph centre lines computed from these fonts by tools/skeleton.py (glyphs.json); outlines are the fonts' own.

VOICE
- English narration: Kokoro v1.0 (kokoro-onnx; model weights hexgrad/Kokoro-82M, Apache-2.0), voice bm_george, speed 0.84,
  through the library's core/tts/tts.py; checked with core/tts/asr_check.py (faster-whisper, MIT; Whisper models, MIT).

MUSIC SAMPLES (CC0 1.0), through the library's core/audio/sampler.py
- contrabass pizzicato, clarinet, bassoon (sustained and staccato): VS Chamber Orchestra: Community Edition (Versilian Studios)
- shaker, claves, woodblock, glockenspiel, harp: Versilian Community Sample Library (Versilian Studios)

SOUND EFFECTS
- Felt-marker strokes, touch-downs, hatch flicks, the peel and the push: synthesised in mix.py (filtered noise and envelopes).

CODE
- Stroke geometry adapted from styles/whiteboard/demo/engine/wb.js. Glyph-skeleton handwriting (thinning a rendered glyph to a
  centre line and walking it as pen strokes) follows the library's sketch-style practice.

NUMBERS ON SCREEN AND IN THE VOICE
