matplotlib markers CARETRIGHT numeric value prop_cycle validation str conversion | matplotlib __init__.py rcParams axes.prop_cycle validate cycler str conversion

Older notes for matplotlib__matplotlib-27613 can help with context, but they do not fully cover the current failure mode.

Why the common answers are incomplete

matplotlib rcParams axes.prop_cycle validation can reject numeric marker constants such as CARETRIGHT after string conversion.

Validate marker values without coercing numeric marker constants into invalid strings, preserving valid MarkerStyle inputs.

The relevant code path includes __init__.py, rcParams, axes.prop_cycle, validate, cycler, and str conversion, so the patch belongs in rcParam validation.
