// Outlook Relook — Selector Registry
// Maps logical element names to resilient CSS selectors.
// Selectors use aria-label, data-*, role, and structural patterns
// to avoid depending on OWA's obfuscated class names.
//
// Selectors marked /* INSPECT OWA */ must be verified against the live DOM.
// Use Chrome DevTools on outlook.office.com to find correct selectors.
