/* ============================================================
   InstallX — shared stylesheet
   Single source of truth for the site chrome (header/footer),
   layout primitives, and ALL responsive behavior.

   Rules of the road:
   - Layout that must change at a breakpoint lives HERE, in a
     class. Never in an inline style (inline always wins), and
     never matched via [style*="…"] selectors.
   - One-off decorative styles (colors, one-off spacing) may
     stay inline in the page.
   - Page-specific responsive tweaks go in a small <style>
     block in that page, using classes — same breakpoints.
   Breakpoints: 1024px (tablet) · 768px (mobile) · 480px (small)
