@bootstrap-wc/core

Base class, controllers, and shared SCSS for Bootstrap Web Components.

• BootstrapElement — light-DOM Lit base class with RTL observer.
• TransitionController — CSS-class transition coordinator.
• FloatingController — wraps @floating-ui/dom for tooltips, popovers, dropdowns.
• FocusTrapController — wraps focus-trap for modals and offcanvas.
• FormAssociated — mixin that turns a LitElement into a form-associated custom element via ElementInternals.

Normally imported transitively by @bootstrap-wc/components. Install directly only if you're building your own components on top of this foundation.
