/* ========================================================================== Alex2MQTT — shared stylesheet Self-hosted, no external fonts or frameworks. System font stack. Light + dark themes driven by the same CSS custom properties.

Site-only tokens: --heading --accent-hover --warn --warn-bg --maxw. Body text stays 16px (a reading page, not a dashboard).
