+Hard baseline (-d / --db-filter / --addons-path / --proxy-mode)
+encodes invariants the v3 deployment relies on (Traefik termination,
+single-DB mode); operators cannot drop these.
+
+Runtime knobs come from .Values.odoo.* and only render when set —
+null leaves Odoo's internal default in place. Overlays without the
+extended odoo block render byte-identical to the pre-runtime-knob
+chart, so B-1 doesn't disturb any live instance.
