The frontend build now emits the sha256 hashes of the inline scripts of every page it writes into resources/public, the image moves them out of the document root, and the entrypoint splices them into the default script-src. This removes one of the two reasons why enforcing mode was not usable.
The hashes are computed on the rendered output rather than on the mustache templates, since the digest covers the exact bytes served between the script tags. All four served pages contribute, not just index.html: challenge.html handles the redirect and render.html and rasterizer.html are loaded by the exporter, so leaving them out would have broken export under enforcing mode. The storybook previews are excluded because that container does not serve them.
A bundle predating this change yields no hashes and the policy stays as it was, so older bundles keep building.

Ship both headers from the image so that every deployment starts from a sensible default instead of each installation deriving its own policy. Report-only mode never blocks a request, so this changes no behaviour for existing deployments, and HSTS stays absent unless PENPOT_PUBLIC_URI declares an https scheme.
The policy can be narrow because the frontend already reverse proxies its own external dependencies, so 'self' covers them. What it must permit beyond that comes from the code: 'wasm-unsafe-eval' for the render engine, 'unsafe-inline' styles for the inline style attributes of the UI, and blob:/data: for thumbnails, exports and fonts.

Move Dockerfile.frontend, .backend, .exporter, .mcp and .storybook
under docker/images/ from ubuntu:26.04 / nginx-unprivileged / a
manual Node tarball install to Docker Hardened Images (Debian 13,
or Alpine for storybook). storybook and mcp get a true non-dev
runtime; frontend, backend and exporter keep the -dev tag as their
final image, since each needs a shell and/or package manager at
container runtime (nginx templating, fontforge/python3, and a
headless-browser stack, respectively).
* ⬆️ Updgrade base image for penpot docker images to ubuntu 26.04
* ⬆️ Update playwright
* 🐳 Use dist-upgrade to update all system packages
