/*
  Design plan (kept here so future edits stay consistent):

  Color   — grounded in the subject, not a generic SaaS palette:
            blueprint navy (#1B3A4B) for structure/brand, safety orange
            (#E85D25) for primary actions and accents, a warm paper/concrete
            background rather than pure white, status colors kept distinct
            from the brand colors so they read clearly at a glance.
  Type    — one system sans-serif stack (fast, and works with zero network,
            which matters for an offline-first field app), one clear scale,
            weight does the differentiating rather than a second typeface.
  Layout  — left-aligned, functional. Thin 1px rules instead of drop
            shadows (a technical/blueprint feel rather than the generic
            soft-shadow card kit). Status is shown with a left accent bar
            on list rows, not just a badge, so a scanned list is readable
            from status color alone.
  Principle — large tap targets and minimal chrome throughout, since this
            is used one-handed, outdoors, on a job site.
