+ * Headless JSON renderer for the site-wide favicon / app-icon set.
+ *
+ * Emits a stable `favicons` object into every page response so the React
+ * frontend can render the <link>/<meta> head tags from the CMS instead of
+ * hard-coding them. The icon files live under public/fileadmin/icons/ and are
+ * referenced root-relative — identical convention to the image URLs emitted by
+ * UsecaseSerializer::image() (getImageUri also returns /fileadmin/... paths).
+ * If the frontend ever runs on a separate origin from the CMS, it must prefix
+ * these hrefs with the CMS base URL, exactly as it does for image URLs.
+ *
+ * Static by nature (same for every page) — no DB access, exception-free.
