The viewBox + bounding rects (in the entviz's own user-units) to ring for a
given walk step, taken straight from the core render model's geometry — so the
React layer never parses the rendered SVG to recover coordinates (and never
touches the closed-profile artifact). One feature may yield several rects
(every blank cell, every quartile cell, both color-bar markers); a probe step
has no figure rect (it shows a planted cell of its own — §14.7).
Takes a PRE-COMPUTED model so a caller stepping through a walk can describe the
value once and map every step cheaply (the per-step mapping is O(cells); the
model build + geometry is not repeated). featureRects is the value-level
convenience that builds the model for you.
