Builds single-file HTML documents: explainers, reference pages, architecture visualizations, light/dark and DE/EN toggles, DESIGN.md tokens. Also running models: simulations with a clock. NOT marketing pages or ops dashboards (creative-design-stack), not ecosystem maps (bridge-explorer). Trigger: "create an HTML page", "explainer", "html kit", "theme toggle", "simulate this".

# html-canvas

Rich **single-file HTML** that reads well, themes light/dark, switches DE/EN and
takes every colour from DESIGN.md: explainers, reference kits, concept and
architecture pages, decision pages, multi-section docs, and simulations that run.
One file, offline, no external dependency, native UTF-8.

This skill also owns the **shared foundation** every HTML skill calls instead of
copying: tokens (`scripts/design-to-css.py`), font embedding
(`scripts/embed-fonts.py`), the quality gate (`scripts/verify-page.py`), the send
bundle (`scripts/bundle.py`) and the theme contract
(`references/theme-contract.md`). `html-slides` builds its decks on them.
