/**
 * IT Live Homepage — Visual Polish Layer v2
 * Laadt NA alle andere CSS zodat verbeteringen overschrijven zonder iets te breken.
 * Kleurenpalet: indigo (#6366f1) + violet (#8b5cf6) + goud (#c9a227)
 *
 * Verbetert:
 *  - Chat bubbles (scherpere schaduwen, betere randen, subtiele animaties)
 *  - Composer/input bar (glass morph, focus ring)
 *  - Action chips (consistent design)
 *  - Buttons (hover states, transitions)
 *  - Navigatie balk (polish, borders)
 *  - Scrollbars (modern thin)
 *  - Form inputs (focus states)
