/*
  Roster CSV import workflow -- Roster Import Foundation Phase 1.

  Loaded alongside styles/v3-app-shell.css in v3.html (after it, so the
  --v3-* custom properties it defines are already in scope) -- this file
  never redefines them and never touches css/styles.css, the legacy Phase
  9.7 stylesheet. Scoped entirely under .v3-roster-import-* /
  [data-roster-import-*] selectors so it can never bleed into the rest of
  the shell, the Force Measurement dashboard's own .v3-fm-* styles, or the
  Force Measurement import panel's .v3-import-* styles -- the two import
  modals are deliberately styled by separate, non-overlapping class
  namespaces rather than sharing one.
