   SECTION 1 - v25, VERBATIM, IN ORIGINAL CASCADE ORDER. DO NOT REORDER.
   Source: _work/inputs/indoorsciences-home-v25.html, md5 e980068b610cd130e2f6c3903527f0d3
   Two <style> blocks, concatenated in document order. Several rules depend on
   equal-specificity source order, so the order here is load-bearing.
   This block supplies all 75 tokens (--w is 1520px, up from the handover's
   1180px, which reflows every page and is intended), the shell, hero, nav,
   footer, buttons, section furniture, and the full breakpoint ladder.

/* --- v25 style block 2 of 2 --- */
  /* ================================================================
     Indoor Sciences · home · v23 (Franz numbering; built on the file sent as v22)
     One stylesheet. Consolidates the v13 base and Franz's V16–V20 layers
     to their final winning values, in cascade order. No behaviour change
     except three fixes noted inline: (F1) .tel nowrap restored,
     (F2) upload drop zone display, (F3) .tri border-top removed as V16 had it, (F4) stray top rule on
     the second diagram reading between 681 and 900px removed.
     v25 · 07 Sep · header separated from the hero: the sticky bar sits on a
     lifted surface (--nav-lift, a color-mix of --ink and --lab, no new hex)
     instead of matching the hero's top stop, and its bottom hairline moves
     from --ink-line to --ink-line-3. Same lift applied to the collapsed
     header and the open mobile menu panel so all three read as one surface.
     Style only. No markup, no copy, no behaviour change.

     v24 · 07 Sep · hero first sentence in --ground; wordmark reveal on
     load (soft-edged mask sweep, 900ms, once, fade-only under reduced
     motion); button hover changed from a cross-fade to a directional
     wipe (in 250ms from the left, out 350ms continuing right).

     v23 · 07 Sep · motion and craft pass against four skills:
     transitions.dev token scale (durations 150/250/350/400/500, 40ms
     stagger, distances 4/8/12px, blur 2/3px, smooth-out easing),
     Emil Kowalski design-eng (UI motion under 300ms, hover under a
     pointer query, no delayed hover-out, press feedback on buttons,
     reduced motion keeps fades), impeccable craft floor + detector
     (AA contrast on light-surface tags, 11px floor in the HUD, themed
     selection/caret/accent/scrollbar, tabular numerals for measured
     values, shadow shape), taste-skill reviewed: its bans on kickers
     and numbered labels conflict with the committed brief and were
     not applied. Layout and copy unchanged.

     v27 (Ninad, 04 Sep f): case-reading severity stamps and the
     0/25/60/100 numerals removed — neither is in V11; the reading is
     the scale plus the measured value, coloured by severity, as V11
     had it. Case plates return to the V11 panel box. Specimen note
     reduced.

     v26 (Ninad, 04 Sep e): ROOT CAUSE of the persistently small
     tags. Archivo carries no true small-caps (no 'smcp' feature), so
     font-variant-caps:small-caps was synthesized by shrinking caps to
     74%: a 12px .sc tag rendered at ~8.9px, while the openers (real
     uppercase since V18) rendered at a true 12px. .sc now sets real
     uppercase, so --tag (13.5px / 12px phone) is the size actually
     drawn, and every tag matches. Severity stamps keep small caps per
     the report spec.
     Fraunces display, Archivo text, Fragment Mono data.
