/* ============================================================================
   FLOTZ — style KAWAII CARTOON B (charte galaxie SANTVIA, porteur 2026-09-11 :
   base canonique de toute la flotte, vague 3 : 17/66, après `echoz`).
   Remplace le glassmorphism premium (backdrop-filter partout, ombres bokeh
   multi-layer, shimmer sweeps) par le patron sticker : aplats + matière 2 tons,
   UNE SEULE ombre plate nette (zéro flou), contour épais, reflet kawaii (2e
   couche de background, jamais en ::after).
   Consolidation : ce fichier était mort (superseded par un <style> inline
   dupliqué dans index.html, même sélecteurs, cascade gagnée par l'inline
   car chargé après) — les deux ont été fusionnés ici en une seule source ;
   le <style> inline a été retiré d'index.html (cf JOURNAL).
   Identité conservée : mer bleu profond (plateau), navires gris ardoise,
   impact corail (--fz-hit), raté bleu ciel (--fz-miss), accent principal
   turquoise (--fz-accent, boutons/HUD), variante « en ligne » bleu roi.
   Thème piloté par le hub via html[data-theme] (posé tôt par /_kit/theme.js,
   cf index.html) — plus d'OS-only @media (prefers-color-scheme).
   Contour : --toon-outline ADAPTATIF (or clair sur panneau sombre, encre foncée
   sur panneau clair) pour panneaux/chips/texte ; --toon-outline-ink TOUJOURS
   foncé pour les éléments posés sur un fond vif (mer, navires, boutons
   pleins) où un contour sombre reste lisible dans les deux thèmes.
