/*
  Chill Brews — site.css
  ======================
  All styling for the single-page site (index.html).

  Reading guide:
    1. Design tokens (:root)  - brand colours + shadow presets, reused everywhere
    2. Base / resets          - sensible defaults for the whole page
    3. Reusable pieces        - buttons, headings, the centred content wrapper
    4. Sections top-to-bottom - header, hero, favourites, menu, story, etc.
    5. Menu marks             - diet dots, spice chillies, allergen icons
    6. Responsive rules       - two breakpoints at the very bottom

  Tip: colours are defined once as CSS variables in :root below. Change a
  brand colour there and it updates across the whole site.
