feat(nav): barre par échelles S / M / XL, tiroir < 1280, fil d'échelle mobile
- NavEchelles : trois groupes (accroche pastille + titre, <ul> étiqueté, aria-current) ≥ 1280 ; groupe courant seul 768-1279 ; lu depuis utils/echelles.ts - NavTiroir remplace le menu déroulant : tiroir à droite, voile, Échap, focus piégé et rendu, cibles 44 px ; bouton « Menu » masqué ≥ 1280 - FilEchelle < 768, dans le flux avant le conteneur de page - Soutenir et À propos dans la barre ≥ 1280 ; Signaler quitte la barre - barre de recherche d'en-tête retirée (/ garde sa recherche dans MobileSheet à 768 et 1000, vérifié au DOM) - html lang="fr" (Lighthouse html-has-lang) B10 M2-M4.

barre (utils/echelles.ts), puis Manifeste, À propos, Signaler, et Soutenir.
