+# Gitea-tvillingen til .github/workflows/ci.yml. Den prøver at nå samme resultat
+# ad en anden vej, og forskellen er hele pointen med filen:
+#
+# INGEN `uses:`. Gitea Actions kan læse GitHubs format, men `DEFAULT_ACTIONS_URL`
+# står ikke i app.ini på gitea.nolimit.dk, og standarden er github.com — så et
+# `uses: actions/checkout@v4` her ville blive hentet FRA GitHub, hver gang, også
+# selvom både koden, runneren og registret er vores egne. Et workflow, der bruger
+# markedspladsen, er derfor ikke uafhængigt af GitHub; det ser bare sådan ud.
+#
+# Prisen er, at værktøjskæden skal komme et sted fra. Den kommer fra jobbets
+# container, hvilket er billigere end det lyder: `container: golang:1.26` er
+# nøjagtig det, setup-go ellers ville bruge et trin på at installere.
+#
+# Alternativerne, hvis nogen senere vil skrive filen om: sæt DEFAULT_ACTIONS_URL
+# til gitea.com, som spejler de gængse handlinger — men det flytter kun
+# afhængigheden fra én andens server til en andens, og det er en indstilling for
+# HELE instansen, altså også for alt andet, der bygger der. Denne fil rører kun
