/* ==================================================
   PRODUCT PAGES v3 (/bulk-sms, /whatsapp-api, /rcs-message, /otp) — shared pieces on top of
   home-v2.css (hero card, glass cards, buttons, channel cards, stats row, CTAs).
   Every page sets its accent from its channel icon through .pv-page--<channel>:
   pills, ticks, tiles, links, step numbers, FAQ chevrons and the sticky bar follow it.
   Classes are prefixed pv-. Page-specific scenes live in <page>-v3.css.
