   Champ à tags. Entrée ou virgule → la chip pop avec un spring (scale 0.6 +
   overshoot) ; × → elle s'éjecte (scale down + rotation + fade) et les chips
   suivantes se resserrent en FLIP (transforms posés par anim.js) ; Backspace
   sur champ vide arme la dernière chip (.is-armed) puis la supprime ; limite
   data-max dépassée → shake du champ. Chaque chip reçoit --tag-mix (variation
   de teinte accent → accent-2) et .is-new / .is-leaving par le JS.
