The drawing-card feature batch (icon/image/compare/graph/d2 cards, --stdin,
tool resolution) added widget + wiring code that dipped total coverage under
the 95% floor — surfaced by `make release` (push-check skips coverage). Cover
the gaps: ProblemsController.refresh, every SVG shape-type bbox + the style
vocabulary, _spawnD2 via a real /bin/cat, the icon-show bus path + error
branches, and quad/arc/close marker paths.

The builder captures data-label / data-description / data-lightbox on SVG
elements into SvgDocument.annotations, each with the element's AABB in
viewBox coordinates (accumulated transform applied — rect/ellipse/image/
line/poly/path bounded; groups skipped, text degenerates to its anchor
point). Feeds the Flutter caption/lightbox overlay next. Flutter-free,
covered by dart test (6 new cases).

Collect <marker> defs (refX/refY, orient=auto, markerUnits) and the path
marker-start/mid/end refs in the builder, then paint them at the path
endpoints rotated to the path tangent (orient=auto). The viewBox→viewport
scale is approximated 1:1 (holds for d2's markers). d2 edges now render
with arrowheads. Covered by dart test (builder) + a flutter-test pixel
probe (the green arrowhead draws). image painting remains the last T-320
follow-on.

The builder ties the five parsers together: parseXml → inlineStyles →
a typed SvgNode tree (group/rect/ellipse/line/poly/path/text/image) with
viewBox, per-node Affine transforms, and inheritance-flattened SvgStyle
(fill/stroke/font resolved to ARGB; opacity per-node). Tolerant — a
non-svg root yields an empty doc; defs/marker deferred. An end-to-end test
runs the whole pipeline against a real d2-rendered SVG fixture. Flutter-
free, covered by dart test (17 cases). No user-visible behaviour yet.

parseSvgColor → packed ARGB (#rgb/#rgba/#rrggbb/#rrggbbaa, rgb()/rgba()
integer or %, common names, none/transparent → 0x0); null on unrecognised
so the caller can inherit. parseTransform → a composed 2-D Affine
(translate/scale/rotate[/about-point]/matrix/skew), applied left-to-right.
Both tolerant and Flutter-free, covered by dart test (22 cases). These feed
the typed node model next. No user-visible behaviour yet.

Zero-dependency, tolerant XML reader (elements/attrs/text/comments/prolog/
CDATA/entities; <style> read as raw text) producing a generic element tree.
The normalizer folds d2/graphviz's class-based <style> rules into inline
presentation attributes — cascade presentation-attr < tag < class < style —
then drops <style>/class/style, so the painter only ever sees inline attrs
(D-103). Flutter-free, covered by dart test (26 cases). No user-visible
behaviour yet.

Parse the `d` attribute into an absolute-coordinate SvgPathSeg list,
lowering SVG shorthands to a small command set the painter can replay:
relative→absolute, H/V→lineTo, S→cubic and T→quad with control
reflection, arcs kept as arcTo. Tolerant — malformed tail returns the
understood prefix and never throws, so a bad diagram can't crash the
conversation. Flutter-free, covered by dart test. First slice of the SVG
engine (D-103); no user-visible behaviour yet.
