/* ==========================================================================
   site.css — per-site layout & components, built FROM tokens.

   HARD RULE (house-tech-spec §3): no raw hex, no px/rem size literals, no
   font-name literals in this file. Tokens only. The Critic greps for it.
   The two escape hatches are the house breakpoints and an explicit
   `@allow-literal: reason` comment on the preceding line.

   WHAT THE SKELETON SHIPS HERE, AND WHY IT SHIPS SO LITTLE
   --------------------------------------------------------
   Only the shell: header/nav, the section rhythm hook, buttons, the form, the
   footer. That is everything a site needs structurally and nothing that
   decides how it looks.

   The skeleton deliberately ships NO hero, NO card grid, NO feature row, NO
   testimonial block and NO section-heading pattern. Those come from the
   approved brief's layout archetype (design-rules §7) and are written per
   site. A skeleton that shipped them would hand every business the same page
   with different colours — which is the exact failure the DNA registry
   exists to prevent, and it would collide head-on with the banned-defaults
   list (design-rules §4: three-card grids, four-stat rows, centred hero with
   two pill buttons, every section the same padding with a centred heading).

   And when a brief's archetype numbers its sections, its sub-lists take a
   visibly different mark — different numeral system, face and colour role —
   or no mark at all (design-rules §4, "two counters in one costume").

   Builder: extend this file with the brief's components. Do not "fill in" a
   hero here from memory — the brief is law (spec §12).

/* QA r3 FIX perf/cls (this skeleton-level defect was confirmed present,
   verbatim, on every site built from it -- see
   runs/3-elements-landscaping-asheville-nc/qa/critic-round-2.md): the
   collapsed state used to apply only once a deferred `type="module"`
   script called `initNav()` and set `[data-nav-ready]`, so the full nav
   list rendered open at first paint and then collapsed into the hamburger
   AFTER first contentful paint -- a timing race with no fixed outcome that
   shifted the whole header (and everything below it) and scored CLS
   0.066-0.094 in the majority of Lighthouse runs. Inverting the default
   removes the race entirely: closed is now the plain CSS default below
   48em, with no JS gate, so there is nothing left to collapse post-paint.
   The one visitor this would otherwise strand -- JS off, so
   `[data-nav-ready]` never lands -- gets the nav back via the <noscript>
   stylesheet override in `@shared:head-boilerplate` (index.html/buy.html/
   thanks.html), which ships last in source order and wins the
   display:block/display:none tie on cascade order alone, no
   `!important`. The nav-toggle button already ships `hidden` in the HTML
   and only JS ever clears that, so JS-off visitors never see a dead
   control -- nothing to change there. */
