home-network-k3s-impl/platform/homepage/deployment.yaml

---
# Homepage (gethomepage) — the apex landing dashboard at https://home.keithjackson.dev. Plain
# manifests (not a HelmRelease): the whole app is a single stateless Deployment + a config ConfigMap,
# and hand-authoring the ConfigMap gives exact control over the service links without guessing a
# chart's values schema (same plain-manifest style as apps/vms/unifi). Rendered by its OWN non-gating
# post-platform Flux Kustomization (clusters/base/homepage.yaml, dependsOn platform-config,
# wait:false) — a leaf UI must never sit in the gating `platform` tier (DECISIONS-LOG: "Headlamp
# gating stall").
