/* ==========================================================================
   Entwine Systems · Store Asset Monitor
   Design system aligned to entwinesystems.com (blue / commercial theme).

   Brand tokens lifted verbatim from the marketing site:
     --navy #0f1b35 · --navy-mid #1e3a6e · --cyan #0ea5c9
     --blue #1d6fa8 · --blue-deep #1e4d8c · --bg #f0f6ff · --bg-deep #e4eef9
   Type: Outfit (UI) · Playfair Display (display) · JetBrains Mono (keys)

   Chart colour is validated, not eyeballed (dataviz six-checks, both modes):
     status ok #0ca30c · warning #fab219 · critical #d03b3b · series #1d6fa8
     CVD separation PASS · normal-vision floor PASS in light and dark.
     Status warning sits below 3:1 on light by design — every status therefore
     ships an ICON + TEXT LABEL, and every chart has a table view. Colour alone
     never carries meaning anywhere in this file.
