Constraint: Static images need to come from remote sources before log sync and build
Rejected: Per-file source mapping | directory-grouped manifests are easier to maintain
Confidence: high
Scope-risk: narrow
Directive: Prefer grouped target_dir manifests and keep page-facing paths stable
Tested: npm run assets:sync; npm run build; bash -n scripts/deploy-homepage.sh; npx tsc --noEmit --pretty false --project tsconfig.json
Not-tested: Real Seafile download against production URLs
