/*
  Pablo* — SHARED STYLESHEET

  Used by index.html and pricing.html. No frameworks, imports or external fonts.
  System font stacks: Arial/Helvetica (body), Georgia (editorial italics),
  Courier New (small editorial notes). Appearance varies slightly by device.

  Quick edits:
  - Colours: the :root variables below.
  - Page width and side margins: .wrap.
  - Main headlines: .hero h1 and .builder-heading h1.
  - Calculator prices: edit the PRICES object in script.js, not here.
  - Phone layouts: the @media(max-width:640px) sections.

  Rules are grouped in page order. Responsive overrides follow their sections.
  Keep this order: later rules intentionally override earlier ones.
