/**
 * School Modern — template stylesheet.
 *
 * Loaded after the shared front-end foundation and before the site's compiled
 * design tokens, so this file can restyle anything the foundation provides while
 * the site owner's colour and font choices still win over both.
 *
 * The rule this template follows throughout: **never hardcode a colour, radius,
 * or spacing value.** Everything reads a custom property. That is the only
 * reason the Live Design Panel can recolour an entire school website instantly,
 * and it is what a third-party template author has to respect too.
