/* ============================================================
   Dang! Payoff — THE STAGE, the calculator pages' approved layout (founder rulings
   2026-09-20A/B/D; the pixel-level authority is _design/calculator-reference.html).

   ⛔ OWNERSHIP BY CONSTRUCTION (ruling 2026-09-20D). css/seo-page.css imports this
   sheet into the top cascade LAYER (`stage`), above `chart` (payoff-chart.css) and
   `base` (seo.css): every declaration here wins over those sheets by layer, never
   by specificity or source order. This sheet owns every element inside .seo-stage
   EXCEPT the chart figure, which payoff-chart.css owns; it never names a .po-chart*
   class (the chart sits in the stage-owned slot .seo-stage__chart). A modifier
   compounds its base class (.seo-stage__hero.seo-stage__hero--flag) so it outranks
   the base at every breakpoint. _design/tools/cascade_audit.mjs measures all of this
   on the served page and refuses a candidate where any owner's declaration lost.
