/* Shared brand-frame primitives (walk remediation C, Section 2).
   The brand frame Scott's marketing home established, de-scoped from .marketing-shell onto the
   neutral .neo-frame wrapper so BOTH the customer app and the operator plane (AdminPortal) render
   it. Source of truth for colors: design-tokens.css (the three-tier green system: green accent /
   spruce chrome / pine surface). Marketing-page-specific styling (hero, hero visual, step cards,
   FAQ, exec pages, SVG illustrations, the dark-hero .btn variants) stays in css/marketing.css.

   The button set here is the .neo-button family, deliberately distinct from the operator .btn set
   in app.css and the dark-hero .btn variants in marketing.css: those two share the .btn names and
   are kept apart only by the .marketing-shell scope (see marketing.css P0-7), so the shared frame
   introduces its own namespace rather than re-scoping .btn and repainting operator buttons. */
