…g and colorbars Add matplotlib-style 2-D plotting backed by GLE's native surface tooling: - imshow(Z): gridded heatmaps via the GLE colormap command and generated .z sidecar files; extent/origin/vmin/vmax/interpolation supported; renders correctly on log axes - contour(x, y, Z): contour lines via begin-contour blocks with explicit or automatic levels and optional inline value labels (clabel) - tripcolor/tricontour(x, y, z): scattered-data variants (e.g. magnetic susceptibility measurements) gridded at GLE compile time by begin-fitz Akima interpolation - no scipy dependency - Figure.colorbar(): self-contained colorbar subroutine with automatic right-margin reservation so single-axes figures no longer clip it - eight palettes (viridis default, magma, inferno, plasma, cividis, coolwarm, gray, rainbow) emitted as self-contained GLE subroutines transcribed from gle-library sources; values clamped to [0,1] so fitz overshoot saturates instead of speckling - mathtext_to_gle(): matplotlib $...$ math in labels is translated to GLE's TeX-like markup at store time (Greek letters, sub/superscripts) - full parser/recognizer round-trip: emitted GLE re-parses into the object model with byte-identical writer-recognizer-writer fixed point; foreign hand-written colormap/fitz/contour GLE is preserved verbatim - full GUI authoring: heatmap/contour series panels (palette, z-range, levels editor, colorbar controls) and scattered x/y/z creation flow in the data manager - guide (docs/guides/CONTOUR_AND_HEATMAPS.md) with an antiferromagnet field-temperature phase diagram worked example, plus runnable examples Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
GLE 4.3.9 built on the macOS ARM CI runners aborts with no error output while rendering scripts containing begin-fitz/begin-contour blocks; the identically pinned Linux build compiles them fine and upstream GLE has no functional changes between v4.3.9 and master, so this is a platform crash in GLE's Akima/contour code rather than a gleplot emission bug. Marks the scattered-data compile test xfail (non-strict) on darwin and adds a tripcolor-only sibling with the same marker so the macOS job's XFAIL/XPASS report shows which GLE stage (fitz vs contour) crashes.

CI experiment result: fitz-only compilation XPASSes on both macOS jobs while the begin-contour script XFAILs, so the platform crash is in GLE's contour stage, not fitz. The tripcolor-only test now runs as a hard assertion everywhere; only the contour-bearing test stays xfail on darwin. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Summary
Adds matplotlib-style 2-D contour/heatmap plotting backed by GLE's native surface tooling, motivated by magnetic field–temperature phase diagrams from susceptibility data:
imshow(Z)— gridded heatmaps via GLE'scolormapcommand + generated.zsidecars (extent/origin/vmin/vmax/interpolation; correct on log axes).origin="lower"is the default (deviates from matplotlib — documented).contour(x, y, Z)— contour lines viabegin contourblocks, explicit/automatic levels, optional inline value labels (clabel).tripcolor/tricontour(x, y, z)— scattered measurement data gridded at GLE compile time viabegin fitz(Akima) — no scipy dependency.Figure.colorbar()— self-contained colorbar subroutine; figure layout reserves right margin so nothing clips.$\chi$-style matplotlib math in any label is translated to GLE's TeX-like markup at store time (gleplot.mathtext_to_gleis public API).docs/guides/CONTOUR_AND_HEATMAPS.mdwith an antiferromagnet H–T phase-diagram worked example;examples/basic/heatmap_imshow.py,examples/advanced/phase_diagram.py.The first commit is pure black formatting of touched modules (quote normalization), split out so the feature diff stays reviewable.
Known limitations
colormapslot limit) — guarded with a clear error.tricontourlevel ranges can't be validated at store time (grid exists only at GLE compile time).begin contourblocks — isolated by CI experiment (fitz-only scripts pass; Linux passes with the identically pinned build; upstream has no functional changes since v4.3.9). The contour-bearing compile test is non-strict xfail on darwin; this is an upstream GLE platform issue, not an emission bug.Test plan
