/* =============================================================================
   net.css  -  the Earthgrid Net framework (EGN) stylesheet, v1.0 (2026-10-07)
   Home: earthgrid.net. No Bootstrap. No jQuery. One file, one set of tokens.

   WHAT IT IS
     Light, Apple-style look taken from the new search look
     (search/css/style-eg-look.css): 1px lines, white space, quiet gray text,
     one blue accent, pill controls. Earthgrid green and orange stay as small
     accents, and the triangle is the signature shape.

   HOW TO USE IT
     - Change a color or size in the :root block only. Nothing below it holds
       a raw color except the triangle gradients and the photo scrims.
     - Every class starts with nf-. Page files never need their own CSS.
     - Rule: apple-first. Reading text stays near 25em (about 50 characters),
       which keeps lines to 9 to 12 words.
     - Dark mode is not shipped. The tokens make it a 20 line job later.
