/*
  Styles for the AI generation modal. Kept in its own file rather than
  appended to assets/styles.css so the core stylesheet stays exactly as
  it was — this feature can be removed by deleting three tags from
  index.html and this folder.

  Everything here builds on the existing .modal-overlay / .modal-box /
  .chip / .btn primitives and the :root purple palette, so the panel
  reads as part of the app rather than a bolt-on.
