/* --- Hero size system (opt-in) -------------------------------------------
   .hero-lg / .hero-md / .hero-sm standardise hero SCALE and SPACING only; they
   never set alignment, colour, background or imagery, so a page keeps its own
   composition. Every value is a custom property, so a page can override one
   step without forking the block. A hero with no size class is untouched.
   Sizing is content-driven (padding + clamp()), never a fixed height, so heroes
   grow when copy wraps or text is enlarged.

   In the THEME, not the marketing layer, because 6 of the 41 .hero pages do not
   load mkt.css. mkt.css keeps hero COMPOSITION; the theme owns SIZE.

   --hero-pb is 0 by default so the next section's padding supplies the gap; a
   hero with its own background band sets it in its page stylesheet.

   Selectors are compound (.hero.hero-lg) so the variant outranks mkt.css's
   .hero rules, which load after the theme. Always use the pair.
   Two-layer model and the migration inventory: docs/marketing-components.md.

   The managed chrome reads a token vocabulary theme.json owns but the raw-HTML

   the chrome paints unstyled. This block supplies that vocabulary from the
   section 1 tokens; it can be deleted with no visual change once the platform
   serializes theme.json.

   Two constraints, both load-bearing:
     * this sheet loads BEFORE commerce-chrome.css, so overlapping rules carry
       one extra class of specificity on purpose. Nothing uses !important;
     * NO backdrop-filter on .site-header — it would make the header the

   3 nav columns); this tenant's footer carries four nav columns, not three, so

   auto inline-start margin on the actions consumes the free space.

   The z-index is REQUIRED BY that move, not cosmetic: once the control sits at
   the right edge it falls inside the fixed drawer's width, and the drawer has
   no click-outside, Escape handler or close button — so without raising the
   control a pointer user could not dismiss it. A flex item honours z-index
   unpositioned, so no position declaration is introduced.

/* --- 16e. Compact managed menu icon: centred, becomes an X, subtle hover ---
   Three defects are fixed together because fixing one exposes the others: an
   inherited span margin stacked with the component's own gap; the component
   only centres the icon below 980px; and a compact icon would collapse the
   60px row, so the row carries a min-height rather than a transform on the
   control.

   The open state is driven entirely by aria-expanded, which the chrome script
   already maintains: NO new JavaScript. Only transform and opacity animate,
   never on the button itself, so no state can move the control or change the
   header height. prefers-reduced-motion keeps every end state.
