+# Self-hosted static build for the obsidian-vault-platform's Tier-A
+# "obsidian-web serverless/OPFS" (plans/obsidian-vault-platform/SPEC.md §2/§4
+# in grepleria/grepleria-configs). Reuses the SAME static-asset pipeline the
+# Cloudflare Workers deployment uses (src/deployments/cloudflare/), because
+# that's the ONLY deployment mode with NO server-side vault storage — vaults
+# live entirely in browser OPFS (see src/deployments/cloudflare/README.md).
+# That property is load-bearing: SPEC's storm table forbids a shared
+# server-backed vault folder across 2+ browsers, and OPFS-only sidesteps the
+# question by construction (nothing server-side to share).
+#
+# The Node.js server deployment (src/runtime-server/server/) is NOT used
+# here -- it defaults new vaults to server-backed storage ('server' vault
+# type, real filesystem), which is the Tier-B (single-writer Coder
+# workspace) shape, not Tier-A (SPEC §1/§3).
+#
+# Stage 1 does the actual "proprietary renderer" pull: the official Obsidian
+# Android APK, extracted + build-time-patched into vendor/obsidian-mobile/
+# (scripts/update-obsidian-mobile.js) -- never committed to this repo
+# (gitignored), never redistributed; it's baked into THIS image only, which
+# is then pushed to the org's own artifact-keeper registry, never a public one.
