   Foundation layer consumed by ALL BD6.x sub-tasks.
   Do not hard-code font-size or spacing values that conflict
   with this scale — extend the scale instead.

   Type scale (8 steps, fluid via clamp where useful):
     --text-xs     ~12px     captions, source citations, micro-labels
     --text-sm     ~14px     small body, nav, pill labels, card meta
     --text-base   ~16px     body paragraphs
     --text-md     ~18-20px  lede / subhead
     --text-lg     ~24-28px  H3 / card headings
     --text-xl     ~36-44px  H2 / section headings
     --text-2xl    ~56-72px  H1 / page hero
     --text-display clamp(72,9vw,110)  hero display — replaces
                                       legacy clamp(64,12vw,200)
   Leading: --leading-tight 1.05 (heads), --leading-snug 1.3,
            --leading-normal 1.5, --leading-relaxed 1.6 (body)
   Tracking: --tracking-tight -0.02em (heads),
             --tracking-normal 0 (body),
             --tracking-wide 0.18em (eyebrows / mono labels)

   Spacing scale (base unit 4px / 0.25rem):
     1=4  2=8  3=12  4=16  5=20  6=24  8=32 10=40 12=48
     16=64 20=80 24=96

   Color palette (kept; surgical contrast fix only):
     --ink     #1A1715  body — ~17:1 on --bg          AA AAA pass
     --ink-2   #5A5048  secondary body — ~7.6:1       AA pass
     --ink-3   #665A4B  TIGHTENED from #8A7F70 to hit
                        WCAG AA on readable text uses
                        (.shift__stat .src etc.) — now ~5:1
                        on both --bg and --bg-2.
                        Chosen path: darken --ink-3 in place
                        (vs. adding a new token) because
                        .shift__stat .src already references
                        --ink-3 and the eyebrow/mono labels
                        also benefit from the contrast bump.
     --ink-4   rgba(26,23,21,0.30)  KEPT as decorative-only:
                        agent-status dots, use__time arrows,
                        compare-list markers, form placeholders.
                        Do NOT use --ink-4 on readable text.

   === BD6.11 — mobile pass ====================================
   Mobile responsiveness pass across all five pages.
   Mandated breakpoints: 320 / 375 / 414 / 768 / 1024+.
   This section is append-only; it overrides earlier rules via
   source-order specificity (and !important where DARK-THEME
   OVERRIDES on L573+ would otherwise win).

   Scope:
     A. Restructure index.html `.system-view` below 768px —
        the absolutely-positioned pentagon overflows narrow
        viewports. Cards stack, SVG hides, height auto.
     B. Touch-target audit — all clickable elements get a
        44x44 min hit area on mobile (WCAG 2.5.5 / Apple HIG).
     C. Type-scale floor — sub-12px text bumped to --text-xs
        below 480px so nothing falls under the BD6.1 floor.
     D. Section padding — fluid `clamp()` overrides for the
        top hard-coded section-level paddings.
     E. Mobile drawer scroll-lock via `:has()`.
     F. Per-page targeted fixes for the worst layout breaks.

   Do NOT inline-style any element to bypass these rules.
   Do NOT modify rules in earlier sections.
   ============================================================ */
