Flux postBuild.substituteFrom is case-sensitive; platform/ components reference
${UPPERCASE} tokens but cluster-vars keys were lowercase -> none would resolve
(literal ${...} would reach the HelmReleases). Uppercased the ConfigMap data
keys + the dev/prod overlay patch paths. Every component ref now resolves;
clusters/dev & clusters/prod build; gate green. Clears the K1 landmine before
any platform un-suspend.

# MERGE PATCH this single ConfigMap — that patch is the *entire* difference between environments.

# Add a knob here (with a base default) before referencing `${KNOB}` in a component manifest, then
|
|
# give each overlay its env-scoped value. Never fork a base manifest to differ per environment.
