/* =========================================================================
   SEIDR LABS — "Fable v2 · Atelier" redesign · 2026-07-12
   -------------------------------------------------------------------------
   Direction: LIGHT-FIRST, warm and premium. Cream paper + rich warm ink +
   deep FOREST GREEN as the primary + BRASS as the single accent. Airy,
   editorial, confident — the opposite of the rejected dark-navy v1 and the
   opposite of monotone: sections alternate cream / deep-green / sand bands.

   House-design standard, named on purpose (silence = slop):

   TYPE (two-font system, self-hosted — nginx CSP is font-src 'self';
   NEVER re-add Google Fonts <link> tags):
     display  Crimson Pro    variable 400–700 (+italic)  headlines, numerals
     body     Manrope        variable 400–700            everything readable
     mono     JetBrains Mono 400/500                     kickers, tags, data

   COLOUR ROLES (all AA-checked on their surfaces; names, never raw hex at
   call sites):
     paper       #faf6ee   page (warm cream)
     sand        #f1e9d7   alternate warm band
     card        #fffdf8   raised card surface
     ink         #23201a   body text        (15.1:1 on paper)
     ink-soft    #5d5545   secondary text   ( 6.8:1 on paper)
     line        #e5dcc6   hairlines
     line-strong #cabfa0   hover borders
     green       #1e4d38   PRIMARY — forest ( 9.0:1 on paper)
     green-bright#2c6a4d   hover / large accents
     green-deep  #12352a   dark band background
     on-green    #f6f1e3   cream text on green bands (11.8:1 on green-deep)
     on-green-mut#c2cdbd   muted text on green bands ( 6.9:1 on green-deep)
     brass       #8a5c14   ACCENT text — AA small on paper (5.3:1)
     brass-bright#c9963a   decorative only: ghost numerals, strokes, on-dark
     ok #1c7c4d · warn #a06414 · danger #b3352e  (status only, never decor)

   SPACING: one 8px scale — 4/8/12/16/24/32/48/64/80/96/128/160.
   RADIUS:  one system — sm 4 (inputs, chips) · md 8 (buttons, small cards) ·
            lg 16 (cards, panels) · pill (tags only).
   SHADOWS: named sm/md/lg — ONLY on the sticky header (sm), raised cards +
            panels (md), and the hero live-board / chat panel (lg). Nowhere else.
   ICONS:   inline stroke SVGs (Lucide-style, 1.75 stroke). Zero emoji-as-UI.
   MOTION:  hero wash drift, brass underline draw-in, live-dot pulse, reveal
            on scroll, card hover lift — every one disabled under
            prefers-reduced-motion.

/* =========================================================================
   RESEARCH / LONG-FORM ARTICLE — appended 2026-07-28 (lane seidr-research-page)
   -------------------------------------------------------------------------
   Extends the Fable v2 system to the research practice: /research.html and
   /research/quantum-brain-report.html. No token is redefined and no rule
   above this banner is modified — this block is PURELY ADDITIVE, so the six
   pages already live keep byte-identical styling and did not need a re-walk.

   Reused from the system above (deliberately, so the pages read as one site):
     .container .section .section-tight .band-sand .band-dark .kicker .lead
     .muted .brass .serif-i .card .btn .btn-primary .cta-row .tag .tag-*
     .kv .feat-list .section-head .reveal .site-header .site-footer

   New here, all verified collision-free against the rules above before use.
   NOTE: .divider is scoped to .portrait upstream, so long-form gets its own
   .rule element rather than silently rendering an unstyled <hr>.

   DISCLOSURE ("progressive disclosure") — 2026-08-02
   -------------------------------------------------------------------------
   WHY: measured on the live site, /research.html was 20 screens of scrolling
   on a 390px phone and /projects.html was 18. The cause was NOT padding
   (measured at 5-7% of page height) -- it was one enormous always-expanded
   block: 69% of research.html and 88% of projects.html. So the fix is to let
   the reader choose what to expand, NOT to delete content and NOT to squeeze
   spacing.

   Native <details>/<summary> on purpose: no JS needed to work, keyboard- and
   screen-reader-accessible for free, and the text stays IN THE DOM so search
   engines still index every word.

   Two skins share one base:
     .disclose--prose  long-form article sub-sections (research.html)
     .disclose--group  project category groups (projects.html)
   Both sit on --paper or --sand bands only; there is no dark-band variant
   because none is used. If you add one, check contrast on --green-deep first.
