/*
 * Shared modal base classes for Paper Assistant.
 *
 * The error dialog (overlays.css), quality-regenerate confirmation
 * (overlays.css), and demo paper picker (demo.css) all share the same
 * backdrop / centred box / header / actions / button shell. These base
 * `.modal*` classes carry the common structure; each modal keeps its own
 * BEM classes for the parts that genuinely differ (header colour, box
 * sizing, button variants).
 *
 * Loaded before overlays.css and demo.css so the modal-specific rules can
 * layer additional properties on top.
