/*
 * forge.css — neutral base styles for the forge UI.
 *
 * Styles every class/id mountForge() emits, with restrained defaults so the reference
 * profile is presentable with no theme. Instances load THIS first, then their own theme
 * stylesheet, and override via the same selectors (CSS source order wins). Variables let a
 * theme re-skin with a few lines.
