/*
  Le panneau du menu mobile (.main-nav) est en position:fixed et coulisse
  hors-écran via translateX(100%) : fermé, il déborde donc réellement d'une
  largeur d'écran sur la droite. Un position:fixed n'est clippé que par un
  ancêtre html/body, pas par un conteneur ordinaire — d'où le besoin de
  clipper ici, à la racine.

  "overflow: hidden" clippait bien ce débordement, mais hidden (comme auto et
  scroll) fait de l'élément un "conteneur de défilement" au sens CSS, même
  sans barre de scroll visible — et un position:sticky ne reste collé que
  tant qu'aucun de ses ancêtres n'est un tel conteneur. Résultat vérifié sur
  mobile réel (DevTools) le 2026-10-05 : l'en-tête restait bien sticky
  d'après les mesures JS (scrollY, getBoundingClientRect), mais le menu fermé
  restait glissable au doigt vers la droite, révélant le hors-écran — les deux
  diagnostics étaient corrects, le bug se logeait entre les deux.

  "overflow: clip" clippe comme hidden, mais sans faire de l'élément un
  conteneur de défilement : posé sur body (horizontal ET vertical, pour éviter
  qu'un seul axe contraint ne fasse promouvoir l'autre en "auto" — même souci
  que hidden), il laisse .site-header sticky passer au travers jusqu'au vrai
  scroll de la page. Ce vrai scroll doit rester porté par html, qui n'a donc
  QUE son axe horizontal clippé : lui poser overflow-y:clip désactiverait le
  défilement de la page entière, body n'ayant lui-même aucun contenu qui
  déborde verticalement.

/*
  Sous ~600px, logo (214px à hauteur 34px) + bouton "Démarrer mon projet"
  (195px) + icône menu (44px) + espacements ne tiennent plus ensemble : measuré
  à 375px de large, l'en-tête débordait réellement de 121px (headerScrollWidth
  496 pour 375 de large) — ce que l'overflow:clip du html/body masque sans le
  corriger, laissant le bouton et l'icône coupés hors champ. Sur un téléphone,
  le bouton fait double emploi avec le menu et les appels à l'action plus bas
  sur la page : on le retire de l'en-tête plutôt que de le rapetisser au point
  de le rendre illisible.
