invalid_cookie_parameter
One of the provided cookies is not valid.

Common causes
- · The cookie is missing the `name=value` pair.
- · Inline HTML or Markdown was captured with a cookie that has no explicit `Domain`.
- · The `Domain` does not cover the page being captured, so the browser never sends it.
What to do
- · Send each cookie as `name=value; Domain=...; Path=/`, the same shape a Set-Cookie header uses.
- · A cookie without `Domain` is anchored to the capture URL — that works for a URL capture and cannot work for inline content.
- · When login still fails with a valid cookie, check `Secure` and `SameSite` against the scheme of the captured URL.
