/* =============================================================================
 * Change Proposal — visual treatment for the `changeProposal` shortcode
 *
 * Three modes (edit / highlight / flag) map to the three annotation
 * patterns (micro-editing / micro-RAGing / micro-flagging). Four statuses
 * (proposed / accepted / rejected / withdrawn) overlay status-specific
 * typography. Mode and status classes compose independently.
 *
 * Used by `src/_includes/parts/change-proposal/{wrapper,edit,highlight,
 * flag}.njk`. Linked once from `parts/base_head.njk` so every page that
 * embeds a change proposal picks up these styles automatically.
