-type window_link_input() ::
          #{session_id := session_id(),
            window_id := window_id(),

Trusted constructor fields for `window_link/1`. Required keys use :=; optional observations may be not_loaded or unavailable. Integral floats are normalized to integers. Runtime validation still checks ranges, IDs, UTF-8 and derived values. Use `new/2` for dynamically validated maps.
