Conversation
PGFPlots does not support 'minor xticklabels' or 'minor yticklabels' as axis options. The _get_ticks() function was generating these invalid keys when minor tick labels were present, causing LaTeX compilation errors: ! Package pgfkeys Error: I do not know the key '/tikz/minor xticklabels' Skip ticklabel generation for minor ticks while still allowing minor tick positions to be set.

Fixes #51
Problem
PGFPlots does not support \minor xticklabels\ or \minor yticklabels\ as axis options. The _get_ticks()\ function was generating these invalid keys when minor tick labels were present, causing LaTeX compilation errors:

! Package pgfkeys Error: I do not know the key '/tikz/minor xticklabels'

Fix
Skip ticklabel generation ({xy}ticklabels=...) for minor ticks while still allowing minor tick positions (\minor xtick=...) to be set. This is done by checking \is_minor = 'minor' in xy\ and gating the label-related code on
ot is_minor.
All tests pass (113/113), ruff and mypy clean.
