 * nonprofittechsupport.ca — Phase 3 stylesheet

 * Design goals: render fast on mobile (Phase 5 E.2 mobile-Perf gap is 100% caused by GoDaddy's runtime JS — this stylesheet ships none),
 * meet WCAG 2.2 AA contrast + spacing (Phase 5 E.1 target), system font stack so no remote font fetches block first paint.
