Status

Blocked on #111 — SvelteKit 3 migration, which is currently blocked on Auth.js compatibility.

Keep built-in, non-customizable error pages until this dependency is resolved. The unpublished Kit 2 implementation has been reverted rather than introducing per-callsite error wrappers or shared error content in healthy pages.

Desired behavior

  • Optional author-managed Markdown for a distinct 404 page and the 5xx class; decide whether a separate remaining-4xx fallback is useful when resuming.
  • Short boolean control for the built-in recovery/home button.
  • Ordinary Markdown only: raw HTML disabled, no authored helpers/directives/interpolation and no asset publication or transformation.
  • Preserve the actual HTTP status and safe built-in fallback when customization is unavailable.
  • Load/cache only the selected error content; do not load or serialize error copy on healthy pages.
  • Leave normal SvelteKit error calls, authentication redirects, JSON/API responses and inline form validation behavior intact.

Implementation direction after #111

Use SvelteKit 3's native unified error hook and error presentation. Do not require every error caller to use an application-specific throwing wrapper. Keep configuration paths/private exception details server-only; only safe rendered copy/settings may travel with a UI error.

Retain built-in fallback for browser-only failures that cannot obtain server content. Verify expected, framework-generated and unexpected server errors, server-backed navigation, HTTP statuses, body/button selection and failure isolation before publication.

Home/feed Markdown sections already landed in #152 and are not blocked or reverted by this issue.
