   Hero · `.tr2` : nuit + projecteur sur rail ; titre, intro, boutons et trois chiffres ; filtres par profil ;
           rail de cartes bleu nuit (résultat en jaune, la carte survolée est éclairée), flèches.
   Puis  : `.trl` (logos + chiffres), `.trcas` (trois cas clients, billets `.trc`), le rideau final `.apf` (apropos.css).

   Portraits : recadrage sur le visage ; noir et blanc doux tant qu'un témoin n'est pas éclairé.
   ≤ 1000 px : tout s'empile ; ≤ 560 px : une colonne, filtres défilants, flèches masquées. */
