/* =====================================================================
   Buckmail — application shell stylesheet.

   Dark, dense, fast. No framework, no build step, no CDN (the CSP in
   lib/auth/bootstrap.php only allows 'self' for styles anyway, so a CDN
   stylesheet would silently fail to load).

   Conventions the PHP side depends on — do not rename these:
     .data-table      every table; makeSortable() in app.js binds to it
     th[data-sort]    'str' or 'num', set by bm_table_open()
     td[data-v]       raw sort value behind a formatted cell (bm_td_num)
     .rate-ok/.warn/.bad   complaint + bounce rate colouring
     [data-fragment]  block that app.js can re-fetch on its own

   Gotcha: tables live inside .tablewrap, which owns the horizontal scroll.
   The page body must never scroll sideways — a dashboard that shifts under
   the cursor is a dashboard nobody trusts.
