/* =============================================================
   ZARAS — /industries — Trade Constellation (v2)
   -------------------------------------------------------------
   v2: Migrated 4 information-tier text uses from --ink-faint
   (~1.7:1) to --ink-label (~6.5:1, AAA on plain bg).
   -------------------------------------------------------------
   Console-framed constellation of 18 trade nodes mapped onto
   6 operating shape anchors. Sibling readout to .field-map —
   reuses corner brackets, dot-grid backdrop, monospace HUD,
   bottom telemetry strip, signal teal active color.

   Tokens consumed (declared on :root in industries.html):
     --bg, --ink, --ink-sub, --ink-mute, --ink-faint,
     --rule, --rule-hi,
     --signal, --signal-ink, --signal-weak, --signal-rule,
     --mono, --sans
