Branding assets (public/, served directly):
- favicon.svg (scalable, primary), favicon.ico (16/32/48 PNG-embedded),
apple-touch-icon.png (180), icon-192/512.png, site.webmanifest. The mark is
the in-app brand glyph (orange Lucide "server" on dark). Wired into both
layouts via a shared partials/head-icons (rel=icon svg+ico, apple-touch,
manifest, theme-color #06080A). nginx serves the manifest as
application/manifest+json.
Never show raw error text (custom messages only):
- Custom branded resources/views/errors/{403,404,419,429,500,503}.blade.php on a
self-contained error layout (design tokens, brand mark, bilingual via
lang/errors.php) — replaces Laravel's default Symfony/whoops pages.
- docker-compose.prod.yml pins APP_DEBUG=false so a prod error can never render a
stack trace (the custom pages show instead).
- Files download error dispatched a bare $e->getMessage(); wrap it in the
localized files.download_failed (consistent with upload/delete).
Verified in-browser: icon links present + all assets 200; custom 404 renders the
branded German message (no raw "Not Found"/trace), responsive at 375, 0 console.
