/* ==========================================================================
   Alba Software Solutions

   Editorial layout on a warm ink ground. Three deliberate choices drive
   the whole look, so change these and everything follows:

   1. Warm near-black (#100e0c) rather than cold grey — reads as paper
      stock, not a terminal.
   2. Terracotta accent — "Alba" means dawn. One accent, used sparingly.
   3. Hairline rules and an asymmetric grid instead of boxed cards. Type
      and whitespace carry the structure; almost nothing is a container.
