   HOLVEM R3 FURNITURE (M5-R1, round R3, 28 Sep 2026)
   Masthead + mega menu + dropdowns, mobile menu, footer, the R3-S3 section-background system,
   the mineral edge band and the R3-S6 hero overlay component.

   HOW IT IS USED
   - apply.py inlines this file (plus grey-fix.css) into a page as <style data-furniture="r3"> at the END of
     <head>, after the page's own <style>. Every rule here therefore wins ties against the r2 furniture CSS a
     page still carries. Inner class names are new (nav-item, nav-panel, mega, drop, mm-*, sf-*) so the old
     r2 rules (.navitem, .sub, .mgroup, .fgrid ...) never match the new markup.
   - Tokens: the page's own :root carries them (home-v2 lineage). The :root block below repeats the same
     values so a fragment or hero-example renders standalone; identical values, no drift.
   - Breakpoints (R1-SITE nav fix kept): the full nav runs from 1320px; the Menu button carries the
     navigation from 1110 to 1319 and below 1110 (mobile). Re-measured with the real Geist, see the report.
   - No em or en dashes in visible copy anywhere in this file's components.

/* ---------------------------------------------------------------- R3-S3 SECTION BACKGROUNDS -------------------
   The Founder: grey bands make the pages look dull. Rule: sections alternate between the surface (#F4F3EF) and the
   raised paper (#FBFAF8). Section rhythm comes from the slim 31deg mineral edge band or from hairline rules, never
   from a flat grey (#E9E7E0 or similar) full-width band. grey-fix.css neutralises the r2 grey classes.

   .sec-surface / .sec-paper   the two grounds. Alternate them; two paper sections in a row take a hairline rule.
   .rule-top / .rule-bottom    a hairline rule between sections of the same ground.
   .band-mineral-edge          the section carries a 6px mineral band across its top (::before). Do not combine
                               with .amb (which owns ::before); use the standalone element instead.
   .band-mineral-edge.edge-bottom   the band sits on the bottom edge.

   dimension hairlines (.hh-lines), the pale left field for copy legibility (.hh-field), then the copy (.hh-copy).
   The field is the raised paper at .96 to .93 alpha under the copy column, so body copy (#3C4147) measures at
   least 7:1 over any photograph, including a black one (measured in hero-example.html; see the report).

/* =====================================================================================================
   HOLVEM R3 GREY FIX (Founder R3-S3: "when the section background goes grey ... makes the pages look dull")
   apply.py inlines this after furniture.css. It neutralises the r2 classes that paint a flat grey
   (#E9E7E0 = --surface-sunken) as a SECTION background, and turns them into the surface ground with a hairline.

   Found by grep across r2/*.html (28 Sep 2026), section-level grey classes actually used on elements:
     .sunk               <section class="sunk">         applications-concrete-soffit, applications-fibre-cement-encapsulation,
                                                        buildings-agricultural, buildings-offices-concrete-soffits (as "depth sunk")
     .survey.sunk        <section class="survey sunk">  applications-metal-roof-underside, -concrete-soffit, -fibre-cement-encapsulation
     .fivesteps          <section class="fivesteps">    applications-metal-roof-underside
     .bays               <section class="bays">         buildings-warehouse-distribution
     .turn               <section class="turn">         systems-condensation-risk-analysis
     .hero (sunken)      <section class="hero">         projects-hub only (the other 26 .hero rules are already --surface).
                                                        NOT neutralised here: a blanket .hero rule would also hit the
                                                        case-study hero (#D8DEDC). The projects-hub builder changes it
                                                        with the new hero (R3-S6).
     nav.index           <nav class="index">            the "On this page" rail: 13 pages (applications, buildings, problems,
                                                        services, systems). A slim grey band; now surface with hairlines.
   Defined but not carried by any element (neutralised anyway so a copied rule cannot revive them):
     .sec.sunken (documents, systems-*, thank-you, upload)   .hero-paper (thank-you, upload)
   Not touched, because they are plates or instruments, not full-width bands: .ledger, .fstrip, .band (a card with a
   plate), .seg, .stage, media placeholders (.tile-media, .fig-media, .rec-media, .door-media, .gmedia) and every
   chamfer ::after that paints the corner cut.

   METHOD. Each neutralised section gets background:var(--surface) AND remaps --surface-sunken to --surface inside
   itself. The chamfer pseudo-elements and placeholders inside those sections paint with var(--surface-sunken) so
   they follow the new ground automatically and no corner cut shows as a grey triangle. Cards inside stay raised
   paper (#FBFAF8) on the surface (#F4F3EF), which is the accepted alternation.
   Rhythm: add class="band-mineral-edge" (furniture.css) to the neutralised section, or place
   <div class="mineral-edge" aria-hidden="true"></div> before it, where the page needs more than the hairline.
