min-version: 5.3.6
min-version-verified: yes
tested-versions: 5.3.6

Empirical floor: 5.3.6.  Phase 9 static analysis estimated 5.3.0 from
the syntax features used (`\procedure`, `\parameters`, `<% if %>`),
but Phase 11 testing found 5.3.0 produces an artifact that fails to
render correctly; 5.3.6 works.  The exact 5.3.x release where the
fix landed was not bisected — for an edition that embeds its TW core
in the release artifact, the min-version is consumed by the editions
tool's phone-home check, not by end users picking a core to install
against.
