/* ============================================================
   JUWEL · Vext Labs — juwel-humanist.css
   The humanist + pixel research-lab layer for the vextlabs.ai
   interior pages: research.html, notes.html, open-source.html.
   (History: this file carried a pre-FACET "Humanist Candy" pass,
   was emptied 2026-07-09, and sat as a 200-not-404 stub through
   the LuxLiq rebrand. research/notes/open-source had drifted onto
   classnames — .archive-entry, .package, .method-item, .status,
   .claim-plate, .lab-note-article, .section-heading, etc. — that
   were never ported to the live vextlabs.css, so they rendered
   fully unstyled. This pass writes the missing rules for real.)

   Brand law:
   - Zero new tokens. Every color/space/type value below resolves
     to --vx-* (vextlabs.css) or the global --paper/--ink/--topaz
     union (juwel-ds.css) — both already cascading wherever this
     file loads. No second palette, no second design system.
   - Amber (--vx-nectar) stays reserved for she-acts/record/focus:
     one hero word per page + the one .button--juwel handoff.
     Status pills, section labels, and card chrome stay ink-toned.
   - No gem/candy/circular-orb imagery on the lab site. The visual
     signature here is square instrument ticks + a faint index
     grid — legible as "lab notebook", not "product surface".
   - Everything is scoped under body.lab so this stylesheet stays
     inert on the ~20 product pages that still link it by relative
     path (about/pricing/signin/etc. — none carry body.lab).
