/* ---------- Netlify "Powered by Netlify" badge ----------
   Not part of this site: Netlify injects <script src="/.netlify/scripts/hud?variant=public"> at its edge on Free-plan
   projects, which adds a fixed bottom-right iframe#nl-badge-frame (z-index 2147483645) that sits on top of the
   bottom tab bar on phones. Proper switch: Netlify → Project configuration → General → "Powered by Netlify badge" (off).
   Until then hide it; its style is set inline without !important, so this wins. */
