v0.3.0

What's New

• Grouped-priors UI — md.ui.create_tabs / create_stack for tabbed/stacked prior panels, with lazy md.ui import (marimo optional for plain import modist)
• Nested prior widgets — hyperprior widgets render as nested tab groups
• Vector RV sizing — create_priors correctly sizes vector priors (shape=, size=)
• Pymc integration — md.pymc.create_priors compiles a sampler from any pm.Model, per-element widgets for dims-valued priors, sample_prior_predictive for xr.DataTree output, set_distributions to rebuild and pm.sample; auto-maps common pymc families, unwraps XRV wrapper ops (pymc_marketing/pymc-extras), and supports pymc.dims xtensor models
