/* ------------------------------------------------------------------------- *
   SmartEMV - global stylesheet.

   Palette: black and white as the main colours, with #d3a243 (gold) and
   #e7dc8e (sand) used sparingly as accents. Minimal, content-centred layout.

   Everything here is class-based on purpose: the backend (website.py) and the
   .function JS files address elements by id (email, password, cap-img,
   cap-input, submit, missing-fields, inactive, unsubscribed, active, ...), so
   no rule below depends on an id and nothing here can break that contract.
   Error divs keep their inline display:none - the JS flips it to "block", so
   .msg must never set a display of its own.
