/* Shared styles for the sub-pages (built, property). Layers on top of
   scrollcraft.css: reuses its reset, tokens, and typography classes
   (.sc-display / .sc-body / .sc-label / .sc-wrap), and re-declares the same
   theme + chrome (header, nav, footer, star-field, buttons) as the homepage so
   the pages read as one site. No scroll engine here — plain static pages. */
