/* H&C — page Téléchargements (/ressources/telechargements/). Se charge après fiche.css et apropos.css
   (`.btn--paper`, `.ex`, `.apf*`).
   2026-10-15 — l'utilisateur a choisi la piste 2 « Le mur de couvertures » parmi les six
   (planche : captures/ressources/planche-telechargements.jpg).

   1. Hero · `.tl` : mur clair + projecteur sur rail ; titre, une phrase, la ligne d'état du formulaire, puis huit
      cartes (couverture dessinée `.tlv`, type, titre, bouton). Le calendrier ouvre la grille sur une carte jaune.
      Le projecteur pivote vers la carte survolée ou au focus (telechargements.js règle --rig-x / --rig-tilt).
   2. Fenêtre `.tld` : le formulaire unique (dialog natif), mémorisé 90 jours ; confirmation dans la même fenêtre.
      `.tlt` : bulle de confirmation des téléchargements suivants.
   3. Comment ça marche · `.tls` : trois temps, photo et « dans une brochure ».
   4. Rideau final `.apf` (apropos.css) puis le pied de page.
