What shipped

Many “tabs” are just clickable <div>s. That breaks keyboard navigation and hides the peer-view relationship from assistive technology. Beat 17 is the real tablist pattern.

Container with role="tablist"
Each tab role="tab" + id + aria-controls → panel
Selection via aria-selected="true/false"
Panels role="tabpanel" + aria-labelledby back to the tab
Roving tabindex: only the active tab is tabindex="0"; siblings -1
Keyboard: Tab reaches the active tab; ←/→ (and sometimes ↑/↓) move; Home/End jump
Activation modes: automatic (focus selects) vs manual (Enter/Space selects) — pick one and stay consistent

Tabs: pick one of several peer views; usually only one is shown at a time, and switching is frequent. Accordion: expand/collapse; users may want multiple sections open, and content is often read in sequence.

Tabs vs accordion

If content is long or users may want multiple sections visible, prefer accordion (beat 15). Tabs are for peer views with frequent switching. Same Channel Hub series, receipts-first GPT-5.2 style. Process journalism; no standing or streak change.
