Engine features, honored by the live client and static SVG/PNG exports alike: - tick_label_anchor on x_axis/y_axis and as a slot style (mpl ha aliases normalize): which label edge pins to the tick; rotated tick labels pivot about the pinned edge. - theme(background=) is the figure background (mpl figure.facecolor), painting the whole card (margins, title, tick labels); --chart-bg / plot_background now scopes to the plot rect only. - Rule/annotation label styling: dash strings, vertical_align, padding offsets. Showcased by the new examples/demo-advance.ipynb (benchmark-style bar chart + ExploitBench line/scatter recreation) and its Chromium-engine PNG build at examples/exploitbench.png.

Arrow labels no longer sit exactly on the shaft midpoint: the client lifts them along the shaft's upward normal so the line doesn't strike through the text (#63). The alignment probe still asserted the old center-x-equals-midpoint contract and failed once a Chromium is available (CI skips these probes). Assert the new geometry instead: no tangential drift along the shaft, and a normal offset large enough that the label box clears the line.

Engine features
Honored by the live client and the static SVG/PNG exports alike:
tick_label_anchoronx_axis/y_axisand as a slot style (mplhaaliasesleft/right/middlenormalize) — selects which label edge pins to the tick; rotated tick labels pivot about the pinned edge. This is the mplha=semantic the pyplot shim emits for slanted categorical labels.theme(background=)is the figure background (mplfigure.facecolor): it paints the whole card — margins, title, tick labels — and shows through the plot rect.--chart-bg/plot_backgroundnow scopes to the plot rect only (mplaxes.facecolor). Static exports reproduce both fills.vertical_align, and padding offsets on annotation labels.Docs updated in
docs/engineering/styling.md; parity tests across components, CSS mark styles, SVG/PNG export, and pyplot layout no-ops.
