/*
  mesh-stage1.css — single canonical Stage 1 stylesheet.

  Loaded by every mesh.* TLD bootstrap (mesh.wiki, mesh.art, mesh.city,
  …) so the inline Stage 1 paint can render hero + tab strip + status
  pill BEFORE the heavy m-mask-renderer.mutual + m-mask-header.mutual
  + m-mask-tabs.mutual finish downloading and parsing.

  Authoritative source for the selectors below — m-mask-header.mutual,
  m-mask-tabs.mutual and m-mask-renderer.mutual reference the same
  rules either by linking to this file or by maintaining a marked
  duplicate. When you edit a Stage 1 selector here, search the three
  mutuals above for the same selector and update both, or drop the
  mutual copy entirely.

   Just enough to make a single-image hero render correctly. The
   collage / credit overlay / initials / metarow / geo styles stay
   in m-mask-header.mutual since they're only needed once the
   mutual is loaded. */
