- Add Arrow key navigation + roving tabindex to all role=radiogroup
components (AutodraftSettings x2, TimerModeSelector,
OvernightPauseSettings, ScoringPresetPicker) per ARIA radio pattern
- Extract shared focus-trap logic into useFocusTrap hook; update
ConnectionOverlay and AuthRecoveryOverlay to use it
- Add tabIndex={-1} to ConnectionOverlay Card so focus can land in
spinner-only state (no interactive children)
- Replace aria-live on loading dots container with sr-only span so
status changes are announced by text content, not aria-label
- Remove contradictory aria-hidden+role=columnheader from
AvailableParticipantsSection visual-only header row
- Remove invalid scope="col" from div[role=columnheader] in
DraftSummaryView (scope is only valid on <th>)
- Remove redundant aria-label from ParticipantSelectionDialog sport
select (htmlFor label is sufficient)
- Change WizardStepper connector <li> to role=presentation
- Revert muted-foreground from 62% to 55% (original already passes
contrast; footer was fixed separately via text-muted-foreground)
