Glowmotion

Create premium animated technical diagrams as single self-contained HTML files. Glowmotion combines a deterministic layout engine (dashmotion lineage: the script computes every coordinate and route, mechanized checkers verify the result) with a lanshu-style premium finish (glow-trail dots, pulsing module halos, grain + vignette, icon glyphs, title capsule) — implemented entirely as vector SVG/CSS/SMIL, so the output stays a few KB, scales losslessly, respects reduced motion, and opens in any browser straight from the filesystem.

Requires python3 (pure stdlib — no pip installs). There is no hand-layout fallback: the engine owns all geometry.
