/* ---------------------------------------------------------------------------
   Aligned with Microsoft Fluent, so the app reads as a tool that belongs next to
   the Azure portal rather than a chat toy.

   Three rules hold it together:
     1. Colour carries meaning. The accent is for actions and the current
        selection only, never decoration.
     2. Monospace is for machine text -- endpoints, JSON, tool names, keys.
        Prose is set in the UI font.
     3. One spacing scale (4/8/12/16/24/32) and five type sizes. No others.

   Morning AI Digest — the published page.

   A publication, not a tool, but no longer a single narrow column: five short
   sections in one column left most of a widescreen empty and pushed the last
   section below three scrolls of nothing. The article now flows into two
   newspaper columns once there is room, each still at a readable measure, with
   every item in its own card so the eye has edges to work with.

   None of the machinery that produced the digest appears here.
