/* ============================================================
   Good Irrigation — shared site stylesheet
   Used by every page: index.html, garden-irrigation.html,
   rainwater-harvesting.html, drought-ready-gardens.html,
   about.html, contact.html, compliance-check.html.

   This file holds only what's common across pages: colour and
   type tokens, base resets, buttons, the sticky header/nav,
   footer, and the mobile CTA bar. Each page's own <style> block
   holds ONLY that page's unique sections (hero, content grids,
   etc.) — so a colour or button change here updates every page
   at once, but a hero layout tweak on one page never touches
   another.
