/* ============================================================================
   Mail Ops — dashboard stylesheet

   An instrument panel for a five-domain sending fleet. Two typefaces, both
   self-hosted: IBM Plex Sans for the interface, IBM Plex Mono for anything
   that is an identifier — addresses, domains, IPs, timestamps, ids. The mono
   is not decoration: `l`/`1` and `O`/`0` are the failure mode in a bounce log.

   Every sending domain carries its own colour, defined once below and reused
   on mail rows, pool cards and the brand mark, so a glance says which domain
   did what.
