/* ============================================================
   components/file.css — Majestic V2 file field & dropzone
   ------------------------------------------------------------
   Track C. Two opt-in shapes, both keeping the native
   <input type="file"> as the submitted source:

     • .majestic-file      compact field — a browse button plus a
                           file name / count and a clear action.
     • .majestic-filedrop  a keyboard/click/drag/drop zone. Paste is
                           accepted only while the zone itself is
                           focused; it never captures page-wide paste.

   Namespaced away from the legacy .majestic-dropzone system so both
   can coexist until the legacy sweep in Phase 10.
