/* ============================================================
   TERRABUILD GLOBAL — site.css
   ------------------------------------------------------------
   THESIS: The site is a specification library: TerraBuild's offer
   rendered as a curated tray of labeled material specimens and spec
   cards. It refuses the category default (dark crane photo, slogan,
   three icon cards).
   OWN-WORLD: brand navy boards with a faint drafting dot grid; cool
   matboard ground; white spec cards with hairline rules and mono
   specimen IDs; procedural material textures in beveled frames;
   orange reserved for action, tabs and hold points. Big Shoulders
   display, Saira body, Spline Sans Mono codes. 2px radii, physical
   shallow shadows.
   STORY: a 35-60 procurement professional sees breadth plus
   documentation discipline, believes the process, requests a quote.
   FIRST VIEWPORT: navy board; positioning left, six-specimen tray
   right; primary CTA orange.
   FORM: Sample Board, candidate 4 of 7, seed a1b41713.
