/* ==========================================================================
   102 — Command Palette
   Palette ⌘K : backdrop blur, panneau qui tombe avec un spring depuis
   -12 px, résultats en stagger, filtrage live (réordonnancement FLIP géré
   par anim.js), surbrillance qui glisse aux flèches, flash accent à
   l'exécution (Enter/clic).
   Racine : .command-palette — états .is-open / .is-closing pilotés par
   anim.js. Démo CONTENUE : overlay absolute dans la racine (relative).
   Voir README pour le passage en fixed plein écran.
