/* =====================================================================
   DUNBEN — Experience Module + stacking interaction
   ONE reusable panel template (.dv-exp) reused by the 3 Experience panels,
   plus the shared stacking stage (card-module base + N panels).
   Animation is driven by js/experience-stack.js using tuned params from
   the stack-playground. Geometry params live here as CSS vars; the JS reads
   the same values. Standalone — NOT wired into app.min.js.
   To add / swap a panel: copy one <article class="dv-exp-panel dv-exp"> block
   and change label / title / desc / images. Everything else is shared.

/* ============================================================================
   Reusable Experience panel content — ONE image + text, two layout variants.
   ----------------------------------------------------------------------------
   Built from the Figma "Dilivery" case portals (Gucci / BI Branding / Amway).
   Same module, two variants:
     .dv-exp--text-left   → text on the LEFT,  image bleeds off the RIGHT
     .dv-exp--text-right  → text on the RIGHT, image bleeds off the LEFT
   The single image keeps `data-depth` so experience-stack.js still applies the
   exact same parallax; the panel-level scale/lift/darken stacking is unchanged.
   Per-instance image geometry is set via CSS vars on the .dv-exp element:
     --media-w  (image width, vw)   --media-x (horizontal bleed offset, vw)
   Typography mirrors the Figma spec (values ÷1920 → vw).
