/* ==========================================================================
   Valencia AI & Automations
   Built on the Valencia design system.

   Structure of this file:
     1. Tokens          — every colour, size and space the site uses
     2. Base            — resets and default element styles
     3. Layout          — the band rhythm and the content container
     4. Header & footer
     5. Components      — buttons, cards, chips, forms, accordion
     6. Page sections   — hero, rule list, steps, stats, pricing
     7. Motion          — scroll reveal
     8. Responsive      — 1024px, 900px, 620px
   Change a token in section 1 and it changes everywhere.
