/**
 * TobiDu-Formularsystem — eigenständiges CSS, theme-unabhängig.
 * Liest, wo vorhanden, die bestehenden TobiDu-Design-Tokens (CSS-
 * Custom-Properties aus tokens.css) mit sinnvollen Fallback-Werten,
 * damit das Plugin auch ohne das Theme funktionsfähig und lesbar bleibt.
 *
 * Update Bericht Nr. 132 — Formulardesign an die Figma-/Custom-Theme-
 * Optik angeglichen (Nunito-Mikrolabels wie .tobidu-kk-info__label,
 * Gradient-Button wie .btn--primary, Badge-Pill-Optik wie .tobidu-pv2-
 * badge, Karten-Schatten aus tokens.css) — bewusst OHNE die dekorativen
 * Shimmer-/Glow-Hover-Effekte des großen .btn--primary (keine
 * unnötigen Animationen im Formular, nur der ohnehin site-weite
 * dezente Hover-Lift).
