/* Inbox Sentinel -- observe-only console.
   Aesthetic: a signals-room / NOC readout for cold-email deliverability --
   dense monospace tables (tabular figures where columns must align),
   a tracked-out uppercase display wordmark, one desaturated phosphor-cyan
   accent for chrome, and the dataviz-skill status ramp (never repurposed
   for anything but HEALTHY/LOW/MEDIUM/HIGH). System fonts only -- no
   external font requests, no build step. */
