/* BlurMailer — one stylesheet, mobile first. Loaded by the frame and the sign-in
   screen from /apps/blurmailer/public/mail.css (BlurPager D336's public/ folder).

   a button states background, colour, border AND radius together
   (BlurPager SKILLS.md, D143/D147). */

   is too faint to read (2:1), so a FILLED teal surface carries dark ink
   (--bm-on-brand, 7:1), and teal TEXT on the page uses a deeper teal of the
   same hue (--bm-accent, 4.6:1 on white). */
