   fully contained within the card width.

   Full width on mobile — large tap target.

   which behavior it uses on its index card.

   .calc-btn-secondary — ghost variant for Reset and for
   handoff links that are not yet available.
   .calc-btn-row       — stacks buttons on mobile, side by
                         side from 480px up.

   9. DSCR COLOR REFERENCE
   These values are applied inline by JS — not as CSS classes —

   Documented here as the single source of truth.
   Keep the JS color blocks in every calculator in sync with this.

   0.750–0.999  #996600   dark yellow — below coverage
   1.000–1.200  #3a7d44   light green — at/just above breakeven
   1.201–1.499  #2d6a35   medium green — solid coverage
