/* PIP landing pages (/pppipo/ and /pppip/) in the approved LINK landing-page look (Tony, 13-10-2026).
   Warm ivory and navy, large calm Chinese headings, one photograph per scene with the words opposite, plain
   thin-line lists instead of boxes, restrained motion that only runs under html.motion (set in <head> unless the
   visitor asked for less motion; a script failure removes it, so words are never left hidden).
   Accent = the locked PIP teal (src/brand-rules.js PPPIP): #2D7A7B on paper, #3DA5A5 on navy. The funding choices
   inside the form keep their own meaning. The form, pricing and modal styles stay inside each page. */
