Unreleased

New Features

• Plotly dual-theme templates — PlotlyConfig now accepts template_dark and template_light dicts that are deep-merged on top of the built-in plotly_dark / plotly_white base templates. User overrides always win; un-set values inherit from the base. Both templates survive theme switches via pywry:update-theme.
