+Individual charts can also be embedded standalone, outside of a dashboard,

append URL parameters to it:

-------------------------------------------------------------------------- |
+| `standalone`    | `0`, `1` | `0`: normal Explore view; `1`: hide the Explore 
header and controls        |
+| `show_download` | `0`, `1` | Show a compact download control (CSV, JSON, 
Excel) on the standalone chart |
+
+`show_download` is opt-in and has no effect outside of `standalone=1`. The 
download control still respects the viewer's `can_download` permission — it's 
hidden for users who lack it even when the parameter is set.

Review Comment:
   Good catch — named the actual permissions now: `can_export_data` on 
`Superset` under `GRANULAR_EXPORT_CONTROLS`, falling back to `can_csv` on 
`Superset` otherwise.

+Unlike dashboard embedding above, this standalone chart URL is a plain page 
load rather than an iframe embed managed by `@superset-ui/embedded-sdk`, so it 
doesn't go through guest tokens or the `dashboardUiConfig` options.

Review Comment:
   You're right, the Embed Code button already covers this — added a paragraph 
on that session-authenticated iframe flow and how it differs from the 
SDK/guest-token path.
