/* SolarSafe Services — main.css — v3.0
   Palette rules (verified against WCAG 2.1):
   - Neon orange #FF3B14 is the ACTION + HAZARD colour only. It appears nowhere else.
     Isolation effect: the CTA is the only element in its colour family on the page.
   - Neon is NEVER placed on mid sage (1.07:1). Only on ivory, cream, ink or deep sage.
   - Body text 4.5:1 minimum. Buttons and large text 3:1 minimum. All pairs measured.
