/* ==========================================================================
   142 — Todo Strike
   Checklist 100 % CSS (checkbox caché + :checked). Cocher : la case pop
   (overshoot) et se remplit d'accent, le check se dessine au stroke, puis
   le texte se barre PROGRESSIVEMENT de gauche à droite (pseudo-élément
   scaleX, origin left), grise, baisse d'opacité et glisse légèrement.
   Décocher : le trait se retire en sens inverse (droite → gauche), le
   check s'efface, le texte se rallume. Compteur « n / 4 terminées » en
   pur CSS : compteurs + :has(), affiché via content. Aucun JavaScript.
