/* ===========================================================================
   TRAVEL BY TAXI - SITE STYLES
   ===========================================================================
   Bootstrap 5 does most of the layout (grid, spacing, buttons, navbar).
   This file adds the Travel By Taxi look on top of it:
     1. Brand colours + font
     2. Header / navigation
     3. Buttons
     4. Sections + headings
     5. Cards, icon tiles, numbered steps, check lists
     6. Notes / callouts
     7. App store badges + phone mock-up
     8. FAQ accordion
     9. Legal pages (Terms / Privacy)
    10. Footer
    11. Animations
   LEARNING NOTE: Change a colour once in the :root block below and it
   updates everywhere, because every rule uses var(--name).
   =========================================================================== */
