   microsoft-page-v2.css — Microsoft SNDS-only widgets.
   INBOX-185 · 2026-05-01

   Chrome (sidebar / page header / detail card / tabs / data card /
   stat strip / pills) lives in postmaster-page-v2.css and is reused
   verbatim. This file adds only what's unique to SNDS:

     • IP grid (Sending IPs latest status)
     • Stat-strip 4-cell variant for IP Health
     • Clean banner (Trap Hits)
     • Summary banner + Alert banner (Reputation Heatmap header)
     • Heatmap grid (7 IPs × 30 days)
     • Advice card (what-to-do guidance)

   Page-prefix `.snd-*` for these widgets so they can't collide with
   `.pm-*` chrome or the legacy inline <style>.
