Subject: [PATCH] ci: pin invariant globalization on the Windows gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The runner reports en-US interactively, but its scheduled task inherits
en-SE (English/Sweden), whose decimal separator is a comma. That broke 40
tests across App/Core/Runtime/UI.Abstractions on number formatting alone
(expected "update:0.25", actual "update:0,25"). Set-Culture does not reach
a task running without a loaded user profile, and a build gate should not
depend on a machine's regional settings regardless.

Note for follow-up: this pins CI only. The underlying culture sensitivity is
real — a Swedish-locale player would see comma-formatted numbers in these
diagnostic strings.
