	/**
	 * Raw default values for every setting, keyed by option ID.
	 *
	 * Single source of truth for field defaults. The field definition methods below
	 * reference this array instead of duplicating literals, and `Options_API` reads
	 * it to resolve a single default without building every field definition.
	 *
	 * Four rules govern this array:
	 *
	 * 1. No translation calls, and no calls to anything that translates. It must be
	 *    safe to invoke before `init` so an option read on the frontend cannot
	 *    trigger a "translation loading triggered too early" notice.
	 * 2. Values are pre-normalised to match what `settings_defaults()` emits after
	 *    its casts — checkbox defaults are `1`/`0`, never `true`/`false`.
	 * 3. Every registered option has an entry, including fields whose definition
	 *    omits `'default'` entirely. Those resolve to `''` in `settings_defaults()`,
	 *    so they need an explicit `''` here or the option silently resolves to
	 *    `false`. Section headers and descriptive text are the only exclusions.
	 * 4. It is deliberately unfiltered. `{$prefix}_settings_defaults` is applied by
	 *    the consumers — `settings_defaults()` and `Options_API::get_default_option()`
	 *    — so it runs exactly once on each path.
	 *
	 * A default that needs translating or computing at runtime cannot live here.
	 * Store the raw base value and let the consumer supply the translated or
	 * computed value as the second argument to the option getter, which
	 * short-circuits the default lookup entirely:
	 *
	 *     $title = get_option_helper( 'feed_title_text', __( '…', 'text-domain' ) );
