/*
  Teaching World — home page (v2).
  Concept: a corrected worksheet. Cool graph paper, deep ink, a pencil-yellow call to action and ONE red-pen device:
  the teacher's ticks that draw themselves next to the hero checklist. Everything else stays quiet and flat.
  Every rule is prefixed with .hv2 so the theme's element selectors (h1..h6, ul, a ...) cannot leak in.
  Dark mode follows the theme switcher (.active-dark-mode). RTL first.
