Performance and Lifecycle

Performance tips

• Keep numSteps moderate (5-10 in most UI surfaces).
• For large headings, increase blur before increasing steps.
• Prefer update() for runtime changes over constant re-instantiation.
• Only enable auto-updates where resize/scroll shifts geometry.

Lifecycle notes

• draw() batches work with requestAnimationFrame.
• enableAutoUpdates() listens to scroll and resize.
• enableMouseTracking() subscribes to shared mouse monitoring.
• destroy() removes listeners and tears down internal references.

Accessibility notes

• In text-splitting mode, Shine sets aria-label on the host element and marks generated wrapper layers as aria-hidden="true", so assistive tech reads the original phrase once.
• The duplicated mask layer is also aria-hidden="true" to avoid double announcement.
