/* Albedo Guard: global styles
   Visual direction: calm, local, trustworthy, quietly technical; the same
   family as Nest (Fraunces + IBM Plex Sans on warm paper), but Guard wears the
   brand blue instead of Nest's teal, so the two products read as siblings, not
   twins.
   Avoid: aggressive gradients, fake 3D, oversized startup claims. */
