/* --- the mark at the foot, fourfold ---------------------------------------
   His word on the footer, 2026-09-06: «enlarge the logo, I would say,
   fourfold. And just make sure it's congruent to other icons and stuff like
   this.» Fourfold is the bar's 40px taken to 160px, and the typed word goes
   with it: half the mark's height here exactly as it is in the bar, 20px on
   40px, so the glyph keeps the triangle's own proportion and the two parts
   stay one object rather than a large emblem beside a small word.

   ONE knob. --foot-mark-h is the mark and everything else derives from it,
   because the scale is the thing he is judging and a scale spelled into four
   rules cannot be turned. site/header.css:33 owns the bar's 40px and is never
   touched; every rule here is scoped to the footer's own brand column.

   Fenced at 861 because below it there is nothing to size: measured on master
   2026-09-06, footer.site-footer is display:none at 768 and 390 on all 38
   routes that carry one, and the phone stack paints footer.foot with its own
   32px mark, which is phone-* territory. The fence is what makes a 160px
   triangle unable to reach a phone even if that layer ever failed to mount. */

     ROW measurement, word beside triangle at nav size, and carried into a
     stack it sets a word 1.75x the width of the mark it belongs to.

     the 195px triangle, 0.963, within 2% of the plate he signed. His eye and
     his logo agree, and neither of them is the bar.

     The 188px is a measurement of THIS face at THIS tracking, not a law: the
     day the type, the tracking or the word changes, re-measure the plate ratio

/* The brand track, given the lockup's own measure as its floor.
   A track whose minimum is 0 lets an unbreakable run cross into the column
   beside it, so the floor is the content's own min-content and the siblings
   give up the difference evenly - the rhythm is theirs: they stay equal to
   each other and the gap does not move. Measured by the browser rather than
   written as a constant of ours, so a font change moves the floor with it
   instead of overflowing silently.

   What it costs, at the word he picked (44px, 188px wide). The floor is no
   longer holding the word - at 188px the word is narrower than the 195.14px
   mark, so the MARK is what asks for the width now, and the floor is idle
   wherever the track is already wider than 195.14px:

     1440   brand 269.578, siblings 179.719   identical to master, idle
     1180   identical to master               idle
      900   identical to master               idle
     1100   contacts ink +0.80px on / only    binds
     1081   brand 186.734 -> 195.141 (+8.41)
            siblings 124.484 -> 122.797       binds
            contacts ink +1.67px on / only

   The 1300 and 1180 band the 4x word opened is CLOSED. The cost is the dense
   six-column footer on / alone; the other three routes overflow identically on
   both trees, which is master's own inherited defect and not this rule's. At
   its worst, 1081, the overflowing ink still clears the next column by 8.22px
   inside a 24px gutter: nothing collides and nothing clips. Verified 2026-09-07
   - Astra SURVIVES, fresh judge PASS-WITH-CONDITIONS.

   Declared here, after both grids and after their 1080 collapse, because the
   selectors weigh the same and source order is what resolves them - the file
   already turns on that, and a floor written above .footer-dense would never
   fire. Two bands, because the grids change shape at 1080 and the floor has

   the run is 188px and this band is idle on every width - the floor stays
   because it is what makes the overflow impossible rather than merely absent. The four-column grid drops to two tracks of 374px

/* --- the phone accordion ------------------------------------------------- */
/* His verdict on the phone preview, 2026-09-03: «the header change it to one
   block, not like a scroll». The block is this footer, and
   refs/vtb/mobile/rec-2 measures the shape at 1290px: hairline separators at
   an exact row pitch of 171 device px, the label vertically centred in the
   row, a 40x22 chevron inset 40px from the right, on a ground sampled at RGB
   (246,246,248) — which is this palette's own --resurs-surface, the token the
   footer already stands on. At 3x that is a 57px row and a 13px inset.

   Three builders raise this markup (site/footer.js and site/platform-chrome.js
   through site/footer-fold.js, and tools/department.template.html by hand) and
   every route loads this file, so the rules live here once.

   The disclosure and its body are SIBLINGS inside the column, never nested:
   measured in this repo's Chromium (130.0.6723.31), a closed <details> hides
   its content through its shadow slot and display:contents on the host does
   not reach that, so a nested body would be missing from the desk footer
   rather than merely folded. Above the breakpoint both dissolve and the column
   keeps today's box tree plus one zero-margin block, which is what makes the
   desk footer pixel-identical. display:contents goes on the fold and the body,
   never on the .footer-col — a grid item that dissolves loses its column. */
