/* ==========================================================================
   MODAL CHROME — single owner of the shared modal component.

   Everything in this file is the shared component. Page CSS may tune layout
   of a modal's *contents*, but must not restyle the chrome itself.

   SoT: variables.css holds --modal-* tokens and the 4-step width scale.
   Structure: .modal > .modal-content > (.modal-header + .modal-body + .modal-footer)

   Rules:
   - no literal shadows / radii here; all come from --modal-* tokens
   - widths come only from --modal-w-sm|md|lg|xl (or --modal-w-fluid)
   - z-index comes only from --z-modal / --z-modal-confirm / --z-modal-top
