CSS Variable Secrets
summary
Demonstrates concrete CSS custom‑property techniques that reduce duplication, create reactive animations and expose clean component APIs: uses pseudo-private variables to avoid repeated fallbacks, registers numeric hue animation with @property to get smooth color transitions, toggles whole declarations and numeric deltas with the Space Toggle pattern plus @supports fallbacks, and implements linear mapping (with counter/reset and integer coercion) to build a fully CSS bar chart. Live tooling includes a scripted demo recorder and slide framework to replay the examples.
