/**
 * Portfolio switcher.
 *
 * Every value a theme is likely to want to change is a --cms-portfolio-*
 * custom property, set on .cms-portfolio or any ancestor. The defaults are
 * deliberately plain: this ships with the site, so it must not fight a theme
 * that has its own opinions about colour and shape.
 *
 * Panels are hidden with [hidden], which the module sets — never with a rule
 * that applies before the JS has run. Until [data-cms-portfolio-ready] is on
 * the root, every panel stays visible and carries its own heading, so a
 * visitor without JS reads a list of labelled sections instead of a blank
 * area with dead buttons.
