   THEME.CSS — Professional corporate theme for Task Reminder
   Clean navy + slate, serif headings, restrained and trustworthy.
   Loaded AFTER Tailwind CDN; a few !important rules recolor Tailwind's
   emerald utilities to navy without editing every template.
   (Filename kept as retro.css so the server link/path stays stable.)
