/*
 * styles.css — Complete stylesheet for StickyWall vanilla JS app.
 *
 * Combines all three Angular CSS sources into a single file:
 *   1. Global styles      (app/src/styles.css)
 *   2. Wall component      (wall.component.css)
 *   3. Sticky-note component (sticky-note.component.css)
 *
 * Every value is ported 1:1 from the Angular version — same colours, sizes,
 * shadows, transitions, fonts, and background pattern.
