/**
 * EnergyCheck Design System — Foundation Tokens
 * Version 1.0 · Shared by EnergyCheck and EC House
 *
 * Token values are extracted verbatim from the EnergyCheck design-system bundle.
 * Do not edit the :root blocks locally — they are the contract with EnergyCheck.
 * EC House-specific component classes live at the bottom of this file.
 *
 * Fonts are self-hosted (assets/fonts/) rather than pulled from Google Fonts:
 * removes a render-blocking third-party request on every page load.
 * Figtree and JetBrains Mono are variable fonts — one file covers weights 300–900.
