/**
 * @oxpulse/chat-widget — i18n locale table.
 *
 * The widget accepted a `lang` constructor/attribute option since W2.1 but never
 * read it for any string — every user-facing string (tombstone, unseal-error,
 * composer, aria-labels) was hardcoded English. This module is the fix: a flat
 * `Record<Locale, Record<LocaleKey, string>>` lookup + a `t()` helper.
 *
 * No external i18n library — the widget is zero-dependency by design and the
 * CDN bundle is size-budgeted (see esbuild.cdn.mjs FF-1 gate, 250 KB gzip).
 * A plain table + `{placeholder}` substitution covers every string this
 * package renders without pulling in ICU/CLDR plural-rule machinery.
 *
 * Interpolation: templates use `{name}` placeholders, substituted by `t()`.
 * Fallback chain: requested locale → `en` (per-key, via `lookupWithFallback`)
 * → the raw key itself as an absolute last resort — `t()` never returns
 * `undefined` or throws.
