Image- and bin-indexed plots have no meaningful x baseline, so the
themed bottom spine kept by use() doesn't apply to them. Adds an
explicit opt-in to disable all spines on such Axes, documents it in
plotstyle/CLAUDE.md, and updates the showcase notebook's colormap and
multi-panel examples to use it.

Introduces a new plotstyle package providing consistent, presentation/thesis-ready
matplotlib figures: a KIT corporate-design color palette (categorical, sequential,
diverging, status), a theme applied via use() (KIT-black bottom spine only, left/bottom
ticks, horizontal gridlines, left-aligned titles, LaTeX text in Latin Modern Sans),
new_figure() with size presets and figure-level title/params subtitles, a
same-size colorbar() helper, style_legend() and panel_label() building blocks, and
savefig(). Ships as an optional "plotting" extra so core gallery installs stay
lightweight, with a full test suite and a runnable example notebook.
