/* Boards UI (static/boards.js).  Every selector is namespaced .bd-*.
   Colours come from CSS variables with fallbacks so a host can theme it:
   --bd-surface --bd-text --bd-muted --bd-border --bd-accent --bd-list-bg --bd-card-bg --bd-height
   Dark: automatic via prefers-color-scheme, or force with data-bd-theme="dark|light",
   or a host class (.dark / [data-theme="dark"]). */
