ContentSlider, Tabs, and Gallery toHtml exports and their inline scripts
now carry ARIA semantics and keyboard support:
- ContentSlider: prev/next arrows and dot buttons get aria-labels, the
slide stack is wrapped in an aria-live="polite" region, and the
decorative chevron icons are aria-hidden.
- Tabs: tablist/tab/tabpanel roles, aria-selected/aria-controls/
aria-labelledby, and Left/Right/Home/End arrow-key navigation in the
inline script. The tab<->panel id scope is now derived from a
deterministic hash of anchorId/labels instead of Math.random, since
the ARIA linking ids must be stable across export runs.
- Gallery: the lightbox overlay gets role="dialog"/aria-modal/aria-label,
Escape closes it, and thumbnails are keyboard-operable (role="button"
tabindex="0" plus Enter/Space handling in the existing delegated
listener).
