   OmegaMailer — application stylesheet
   --------------------------------------------------------------------------
   Written from zero. The old sheet (legacy.css) is imported into a cascade
   layer from header.php, so every rule here wins over it regardless of
   specificity; it exists only to hold layout glue for tool pages that have
   not yet been rebuilt on these components.

   Identity in one line: editorial serif titles, warm paper, ink-black
   primaries, one teal signal reserved for what is active or positive.
