   Home Resilience Studio — by BYOP Electric
   hrs.byopelectric.com

   A twist on the BYOP homepage "Light Trade" system. Same bones —
   one oversized mark as the page signature, one accent per screen,
   sentence-case display type, a dark slab where the page turns
   serious — retuned for an architectural audience:

     Light Trade            HRS
     -----------            ---
     neutral gray #F5F5F5   warm limestone #F4F1EA
     pure black slabs       slate blue-gray #2E343A
     yellow #FCCE08         restrained copper #A2603A
     Barlow Condensed 600   Newsreader (editorial serif)
     the BYOP bolt          a drafted house elevation

   The drafting register is the other half of the twist: hairline
   rules, dimension ticks, sheet-style section numbers in the margin.
