Menus are lightweight illustrative patterns. Dialogs and drawers use native modal focus containment and Escape. A production application should add its own menu keyboard navigation and routing. No live preview sends or purchases anything.

Every component, in context.

Buttons

Primary is for one leading action per surface. Secondary is for peer actions. Destructive uses semantic red, never the brand gradient.

Keyboard: Tab to interactive controls. Enter activates buttons and links; Space toggles native choices. Disabled controls cannot be activated. Use Escape to close modal surfaces.

Copy implementation markup
<div class="l-demo l-actions"><button class="l-btn l-primary" @click="showToast('Primary action selected')">Primary action</button><button class="l-btn l-secondary" @click="showToast('Secondary action selected')">Secondary</button><button class="l-btn l-quiet" @click="showToast('Quiet action selected')">Quiet</button><button class="l-btn l-danger" @click="openNative('modal',$event)">Delete...</button><button class="l-btn l-secondary" disabled>Disabled</button></div>

Button group

Button group chooses one mode; the adjacent dropdown holds secondary actions.

Alerts

Alerts occupy the page and stay until dismissed. Notifications need a clear source, severity and next action. Do not use color alone to explain the state.

Saved

Your changes are up to date.

Toasts

A toast confirms a short-lived result; it must never be the only place for an error that needs fixing. Trigger several in quick succession: each one stays visible independently until dismissed or its six-second timer ends. Color, a label and a message communicate the variant together.

For production, keep independent IDs and timers so a new arrival never overwrites an earlier one. Render the stack in a portal above app content, cap its height and let it scroll on small screens. Keep errors that need user action inline too; the toast is only a short announcement. Respect reduced-motion when animating entry and exit.
