/**
 * Grid chrome localization. Every user-visible UI string the grid renders itself
 * (empty state, tool panel, pager, status bar, group labels, filter operators,

 * defaults. Pass `localeText` on `<SvGrid>` to override any subset; unset keys
 * fall back to English, so omitting `localeText` is a no-op.
 *
 * This mirrors the editor kit's `resolveMessages` pattern (editor-contract.ts) so
 * chrome and editors share one localization idiom.
