/* ==========================================================================
   Modals — collision-safe modal shell family
   ========================================================================== */

/*
  Modals owns overlay/shell anatomy only.

  This file intentionally uses the md-modal namespace and must not target or
  redefine existing live selectors such as ds-modal-shell, ds-modal-backdrop,
  ds-modal-head, ds-modal-body, ds-modal-actions or ds-modal-close.

  Modals consumes:
  - Typography foundation for title/support/meta roles
  - Colour foundation for surfaces, text and borders
  - Controls for buttons, dropdowns, async status, retry and skeleton
  - Questions for inputs, textareas and answer assemblies
  - Helper Notes for semantic notes
  - Review/Sanity/Project content components where feature-owned content appears
