- Add CSP3 support for style/script: include -elem and -attr directives
- Base (style-src, script-src) now unions elem/attr (CSP2/Safari fallback)
- Respect explicit base disables (e.g. style-src.unsafe-inline: false)
- Hashes only when 'unsafe-inline' absent in the final base tokens
- Nginx: set CSP only for HTML/worker via header_filter_by_lua_block; drop for subresources
- Remove per-location header_filter; keep body_filter only
- Update app role flags to *-attr where appropriate; extend desktop CSS sources
- Add comprehensive unit tests for union/explicit-disable/no-mirror-back

- sys-front-inj-logout: depend on web-svc-logout (run-once guarded) and simplify task flow.
- web-svc-logout: align feature flags/formatting and extend CSP:
- add cdn.jsdelivr.net to connect/script/style and quote values.
- Nginx: move CORS config into logout-proxy.conf.j2 with dynamic vars:
- Access-Control-Allow-Origin set to canonical logout origin,
- Allow-Credentials=true,
- Allow-Methods=GET, OPTIONS,
- basic headers list (Accept, Authorization),
- cache disabled for /logout responses.
- Drop obsolete CORS var passing from 01_core.yml; headers now templated at proxy layer.
Prepares clean cross-origin logout orchestration from https://logout.veen.world.
