/*
  Transaction Calendar v2 — mobile-first CSS
  PASS 1 CLEANUP

  Goals:
  - Stop overlapping layers (header vs overlays)
  - Make the calendar grid clearly visible again
  - Make the form overlay scrollable and usable on small screens
  - Remove duplicate/conflicting auth styles (your file had two different auth blocks)
