/* ===========================================================
   The b2b page in MS-DOS mode (html.dos: the badge, ?dos, or a session
   already in text mode) — B2B SaaS as it would have shipped on a VGA card.

   The spirit stays: gradients everywhere, pills, glowing gradient text,
   the chat bubble, the toasts, the scroll reveals. Only the medium changes:
   the IBM VGA ROM font (dos.css) at whole pixels (16 / 32 / 48 px), the
   16 EGA colours, gradients as hard EGA bands, pills with staircase pixel
   corners, soft blurred shadows as hard black offsets, cards as text-mode
   windows. b2b.html and b2b.js are untouched.
