/* ──────────────────────────────────────────────────────────────────────────
   Feature pages — features.php, ai-modules.php, ai-tasks.php, ai-skills.php

   These four are the deep reading the home page deliberately does not carry.
   They share one namespace (.fp-) and take every colour from tokens.css, so
   light, dark and OLED all resolve without a second palette here.

   Layout rule of the file: sibling groups are spaced with flex/grid `gap`,
   never per-element margins, and anything that can outgrow its track
   (tables, long title lists) scrolls inside its own container rather than
   widening the page.
