Two-column grid: vertical timeline (5 stages with per-stage timestamps)
on the left, grouped document panel (4 categories) on the right. Hero
header carries WO ref + part / qty / ETA / tracking facts.
Controller adds stage_timeline, doc_groups, and timeline_spine_pct
to the render context. Spine fill = done + half-credit for the
active stage (so the spine visually leads the eye to where the work
is happening).
