+drawn at 40 × 30 px (twice the orbital readout's 20 × 15) in sorted code

+**Source:** the 4:3 SVGs of [flag-icons](https://github.com/lipis/flag-icons)

+
+**License:** flag-icons is MIT licensed (© Panayiotis Lipiridis). Country
+flags themselves are not copyrightable designs in most jurisdictions.
+
+**Regenerate:** `node scripts/build-owner-flags.mjs` (after adding an owner
+country, or updating flag-icons). With the same flag-icons and sharp versions
