 ## [development]
 
+### Fixed

+- **`web/templates/*.jinja` missing from distribution wheel** — added `web/templates/*.jinja` to `[tool.setuptools.package-data]` in `pyproject.toml`. After a fresh install from PyPI the admin panel returned 500 because `Jinja2Templates` could not find any templates.
+- **Duplicate `script-src` / `style-src` in admin CSP** — the nonce-augmented directives used to be *appended* after the base ones, so the browser (which honours the first occurrence) ignored the nonce and blocked every inline JS/CSS. They are now *replaced*: `script-src` and `style-src` are filtered out of the base CSP and the nonce versions are appended as the only occurrence.
+- **CSP nonce generated after template rendering** — `request.state.csp_nonce` is now set in `GlobalSecurityHeadersMiddleware.dispatch()` *before* `call_next(request)` so templates see it during rendering. Previously it was generated afterwards, so `csp_nonce` was an empty string in the template context and every inline script was blocked.
+- **Missing `nonce` attribute on `<script>` in `list.html.jinja` and `settings.html.jinja`** — inline scripts in these templates now carry `nonce="{{ csp_nonce | default('') }}"` so they match the nonce in the CSP header.
+- **Bootstrap `admin.password_hash` ignored when `users.toml` is empty** — `Users.all` now falls back to the bootstrap admin even when `users.toml` exists but is empty (e.g. right after `volumen init`, which creates the file via `Path.touch()`). Previously the first login after a clean install failed.
+- **`admin_context` did not pass `users_exist`** — the login page showed the “No users configured” warning even when authentication worked. Added `"users_exist": users_obj.any` to the admin template context.
+- **Inline `style="..."` blocked by strict admin CSP** — the admin templates used inline `style="..."` attributes (and one `card.style.display = ...` JS assignment) which the new strict `style-src 'self' 'nonce-…'` directive blocks. Replaced every offending attribute with a utility class in the `<style>` block (`page-head-actions`, `form-options`, `form-inline`, `form-hidden`, `form-spaced`, `flex-spacer`, `btn-static`, `btn-danger-text`, `text-fg-strong`, `badge-inline`, `h3-section`, `mt-3`, `is-hidden`); the dynamic `background-image: url(...)` on `.post-cover` now flows through a `--cover-url` custom property (`style="--cover-url: …"`) which CSP3 does not treat as an inline style application.
+- **`/favicon.ico` returned 404** — browsers auto-request `/favicon.ico` even when the page declares an explicit `<link rel="icon">`. Added a tiny route in `create_app()` that serves the packaged `web/static/volumen-icon.svg` with `Content-Type: image/svg+xml` and a 1-day `Cache-Control`; added the matching `<link rel="icon" type="image/svg+xml" href="/favicon.ico">` to the admin layout so the tab gets the volumen icon instead of a generic placeholder.
+- **Sidebar version label rendered as bare `v`** — `admin_context` did not include the package `VERSION`, so the footer `<div class="sidebar-version">v{{ version }}</div>` rendered as just `v` with no number behind it. Added `"version": VERSION` to the context.
+
 ## [0.4.1] — 2026-07-27
 
 ### Fixed
 
-- **CSP nonce chybí pro `style-src` v admin routách** — přidán `style-src 'self' 'nonce-{nonce}'` do CSP hlavičky pro `/admin` routy. Bez nonce prohlížeč blokoval všechny inline `<style>` tagy v admin šablonách.
-- **`web/static/` SVG soubory chybí v distribučním kole** — přidána sekce `[tool.setuptools.package-data]` do `pyproject.toml`, aby `volumen-icon.svg` a `volumen-logo.svg` byly součástí instalovaného wheelu. Admin panel dříve vracel 500 na `/admin/icon.svg` a `/admin/logo.svg`.
+- **Missing CSP nonce for `style-src` on admin routes** — added `style-src 'self' 'nonce-{nonce}'` to the CSP header on `/admin` routes. Without a nonce the browser blocked every inline `<style>` tag in the admin templates.
+- **`web/static/` SVG assets missing from distribution wheel** — added a `[tool.setuptools.package-data]` section to `pyproject.toml` so `volumen-icon.svg` and `volumen-logo.svg` ship inside the installed wheel. The admin panel previously returned 500 on `/admin/icon.svg` and `/admin/logo.svg`.
