/*
 * ToneSoul Council — Demo UI v0 styles.
 *
 * Design notes (2026-04-19, Claude Code):
 *   - Perspective decision chips use four distinct hues (approve/concern/
 *     object/abstain). The verdict badge uses the same palette plus a
 *     distinct colour for "declare_stance" and "block".
 *   - No fancy fonts or icon packs — system font stack so the page renders
 *     identically from file:// and GitHub Pages without asset waterfalls.
 *   - Dark mode mirrors the light palette by shifting lightness, not hue, so
 *     the semantic colour mapping stays stable.
