   Color:  Slate navy #1B2A41 (headers/nav), Storm gray #3E4C59 (body text),
           Copper #C1652F (primary accent/CTA), Weathered gold #C9A24B (secondary accent),
           Ivory #F6F2E9 (background), Cloud white #FFFFFF (cards)
   Type:   Oswald (display, condensed/rugged) + Source Sans 3 (body, readable)
   Signature: the "shingle row" divider — overlapping trapezoids that mimic
              a course of roof shingles, used at section breaks instead of
              a generic gradient or wave.
