// Shared chrome for every page: theme toggle (the original deliberate
// exception to "no JavaScript" in this design system) plus copy-to-clipboard
// on terminal blocks, added for the same reason -- both are small, page-wide
// behaviors that don't belong duplicated inline on every page.

// Theme toggle. Defaults to the OS preference (handled entirely by CSS media
// queries; no attribute is set on first load) and only writes data-theme
// once the visitor actually clicks, so a stored choice can override the OS
// setting on return visits.
