/* ============================================================
 * ANSOFTIO Design Layer 2026
 * ============================================================
 * Modern senior-dev design pass that enhances all existing pages.
 * Loaded LAST so it takes precedence over older asf-*.css rules.
 *
 * Approach: progressive enhancement — never break older rules,
 * just refine typography, depth, motion, micro-interactions.
 *
 * Patches applied:
 *   1. Refined design tokens (spring-easing, motion-blur, etc.)
 *   2. Typography rhythm (line-heights, letter-spacing, font-features)
 *   3. Hero — glass-morphism + animated gradient mesh + floating cards
 *   4. Cards — soft 3D tilt-on-hover, subtle shine sweep
 *   5. Buttons — gradient sheen, press-feedback, focus ring
 *   6. Section headers — accent dot + uppercase label rhythm
 *   7. Service / Course / Internship card polish
 *   8. Reviews placeholder polish
 *   9. SaaS product cards — depth + glass overlay
 *  10. Footer — refined dark layout + social icon hover lift
 *  11. Dashboard sidebars — refined active state + micro-spacing
 *  12. AI Chatbot — modern bubbles, gradient glow on focus
 *  13. Forms — refined inputs, validation states, button-loading
 *  14. Scrollbar refinement (webkit)
 *  15. Reduce-motion respect
 * ============================================================ */
