/* HopWarden — shared styles.
   Extends the MAH7 gate page's language: white ground, #111 ink, hairline
   #ddd rules, small restrained type, generous air.
   The one deliberate addition is a monospace display face. That isn't
   decoration: the product is a network sensor, and the MAH7 gate itself
   switches to monospace the moment input looks like a code. The idiom is
   already the brand's. No webfonts — the edge serves static files only,
   and every face below ships with Windows or macOS. */
