 * ROMA Lab – styles.css
 * -----------------------------------------------------------------------------
 * Purpose: Main site stylesheet for ROMA-AI-Lab.github.io
 * Author: (kept as original project authors)
 *
 * Maintainability Notes (non-functional changes only):
 * 1) We do NOT change selectors, property values, or cascade order.
 * 2) We keep existing visual effects 100% intact.
 * 3) We add clear section banners and an index for quick navigation.
 * 4) We normalize minor whitespace and ensure consistent indentation.
 * 5) We avoid @layer / @import or any splitting that could affect cascade.
 *
 * Quick Index (search with your editor):
 * [RESET].............. Base reset & typography
 * [THEME].............. Theme tokens (dark/light) & smooth switching
 * [LAYOUT]............. Container, sections, grids
 * [GLASS].............. Glass–matte tokens & placeholders
 * [MEDIA].............. Avatar / project cover
 * [HEADER]............. Sticky header / nav / drawer
 * [HERO]............... Hero section
 * [BUTTON]............. Buttons / chips / controls
 * [CARDS].............. Cards & metrics
 * [PUB]................ Publications list
 * [SCROLL]............. Vertical scroll containers (news, etc.)
 * [FOOTER]............. Footer
 * [RESPONSIVE]......... Media queries
 *
 * Z-Index reference:
 *   60  - mobile drawer
 *   59  - drawer overlay
 *   50  - sticky header
 *
 * Breakpoints reference:
 *   ≤1100px, ≤900px, ≤780px, ≤720px, ≤520px
