The single large polish pass Jeroen requested off the T-1170 captures,
benchmarked against RimWorld's world-map fluency. Courses now draw as
source-tapered ribbons: per-vertex width ramps from a hairline at the
upstream source to full class width over 15% of the course's arc length
(arc-length parameterized, not vertex-indexed, so point density doesn't
change the read), built as one draw_polygon ribbon with mitred joins.
Class width table retuned 0.9/1.4/2.2 -> 0.6/1.2/2.4: a clean ~2x
per-class ladder so a tributary-joins-trunk confluence reads as a join,
trunk held at its visually-proven weight, stream thinner per the
benchmark's thin/consistent/restrained grammar. Opacity untouched
(Araminta's T-1170 ruling stands). Coast-gradient item resolved as
already-correct (the coastal transition zones + elevation lightness
render the shoreline band; capture-verified) — no wire change. Stipple
assessment filed as T-1194. Eight new taper-geometry tests.
