Klarbild 1.0.0 — first public release

A self-hosted print studio: images at exact physical sizes, sheet layout with
crop marks, tiling, 1:1 PDF. Everything else — image generation, delivery,
share links, mail, Telegram — is an optional module that is off by default.

This is the neutral public twin of a private tool. Compared to that original:

- optional modules behind KLARBILD_MODULES; the default install is print-only
- English interface with German as a full second language (1,038 strings);
  the English sentence is the translation key
- no built-in accounts — first boot creates one admin from ADMIN_USERNAME /
  ADMIN_PASSWORD, or generates a password and logs it once
- delivery and backup targets are generic SFTP/FTPS endpoints, off by default
- English routes, English identifiers, English comments throughout
- two compose files: print-only by default, everything in the full one
- AGPL-3.0, CI (build, tests, type check, secret scan), CONTRIBUTING, SECURITY

124 tests green, type check clean, verified end to end against a live instance.

+# Changelog
+
+## 1.0.0 — first public release
+
+The first open-source release of Klarbild. Everything before this lived in a
+private repository as a personal tool.
+
+**New in the public version**
+
+- **Optional modules.** `KLARBILD_MODULES` decides what an instance is. The
+  default is the print studio alone — no image model, no object store, no bot
+  token, no account anywhere. See `src/lib/modules.ts`.
+- **English interface**, with German as a full second language. The English
+  sentence is the translation key; 1,038 strings.
+- **First-run setup.** No built-in accounts. The first boot creates one
+  administrator from `ADMIN_USERNAME` / `ADMIN_PASSWORD`, or generates a password
+  and prints it once to the log.
+- **Two compose files.** `docker-compose.yaml` is the print-only stack (app plus
+  Postgres, files on a volume); `docker-compose.full.yaml` adds MinIO and every
+  module.
+- **Delivery is generic.** The delivery and backup targets are plain SFTP/FTPS
+  endpoints you configure, switched off by default.
+- English routes: `/print`, `/library`, `/queue`, `/shares`, `/help`, `/account`,
+  `/tour`, `/password`.
+- AGPL-3.0, CI (build, tests, type check, secret scan), `CONTRIBUTING`, `SECURITY`.
+
+**Carried over from the private tool**
+
+The print engine as it stands: 86 image sizes in 10 groups, 19 paper formats
+including A3+ and photo paper, corner marks and continuous lines, bleed 0–10 mm,
+crop or letterbox per picture, oversize as fit / overflow / tile with glue flaps
+and page numbers, captions in six positions, duplicate cells, presets, and a run
+history that stores the instructions rather than the PDF. Plus the optional
+modules: image generation, delivery, backup mirror, share links, mail, Telegram,
+and an MCP server for assistants.
