/**
 * Shared ARIA attribute key normalisation helpers.
 *
 * Two flavours are needed across the codebase:
 *
 * - `normalizeAriaKey`  — always adds the `aria-` prefix for non-role keys.
 *   Used by `aria()` and `bind({ aria: ... })`, where every config key is an ARIA attribute.
 *
 * - `normalizeHostAttrKey` — passes non-ARIA keys through unchanged.
 *   Used by `host.bind({ attr: ... })` where keys may be arbitrary HTML attributes.
