   OUTDOOR DEVS — home.css
   SWITCHBACK: first light to last light.
   Scrolling is hiking — dawn trailhead → switchbacks → summit panorama →
   golden-hour field notes → night campfire. Geist = landscape voice,
   Geist Mono = instrument voice, blaze orange = the trail.
   Interior pages keep css/style.css; this sheet is the homepage's own.
