/* NMER Conservative Visual Upgrade, 2026-10-19
   This stylesheet is purely presentational. Existing Bootstrap, page templates,
   content, data tables, forms and scripts remain unchanged.
   To roll back: remove the stylesheet link from includes/header.php and
   the two independent verification templates. Contact additions remain.
