/* ==========================================================================
   AMQ Härtegrad-Rechner (Mattress Firmness Calculator)
   ==========================================================================
   Premium Light-Theme component for calculating mattress firmness grades.
   Uses BEM naming with `amq-hr` prefix.

   Compact form: two number fields, sleep-position buttons and a submit
   button. Pressing "Empfehlung berechnen" swaps the form (.amq-hr__form) for
   the result view; "Angaben ändern" swaps back. The active view is driven by
   data-view on the .amq-hr root.

   Data-state driven result display:
     data-state="found"      → accent badge with the single grade
     data-state="transition" → accent badge for a Grenzbereich grade
     data-state="not-found"  → subtle warning
   ========================================================================== */
