 * ════════════════════════════════════════════════════════════════════
 *
 * This file controls ALL the visual styling for the Aaral website.
 * It is organised into clearly labelled sections so you can quickly
 * find and edit any part.
 *
 * How CSS works (quick primer):
 *   • A "rule" looks like:  selector { property: value; }
 *   • The selector targets HTML elements (by tag, .class, or #id).
 *   • Properties control colour, size, spacing, layout, etc.
 *   • Comments like this one start with  /*  and end with  * /
 *
 * Section index:
 *   1.  VARIABLES & RESET
 *   2.  TYPOGRAPHY
 *   3.  TOP BAR
 *   4.  BANNER CAROUSEL
 *   5.  SECTION HEADERS
 *   6.  CATEGORY CARDS
 *   7.  SERVICE CARDS
 *   8.  FLOATING BOTTOM NAV
 *   9.  CONTACT POPUP
 *   10. CONTACTS PAGE
 *   11. UTILITY CLASSES
 *   12. ANIMATIONS
 *   13. RESPONSIVE — 640px
