   ERIC THE HEATER GUY — "Ember Ledger" design system
   Structural re-layout. Orange leads. Sentence case. Human-made.

   PATTERN LIBRARY (vary per page — never the same rhythm twice):
   .hero-min / .hero-split   ultra-minimal heroes
   .eyebrow                  mono label, varied text, never formulaic
   .proof-band               ruled fact strip (no checkmarks)
   .ledger / .ledger-plain   ruled rows replacing card grids
   .split-uneven             asymmetric 7/5 image+text
   .statement                big single sentence + CTA, huge whitespace
   .field-note               inset margin-note block
   .faq-ruled                ruled FAQ rows
   .cta-offset               card that breaks the grid
   .duo                      two large editorial rows (not 4 cards)
