The card schema was looser than the stored question's depends (up to 8 Lines of
at most 1,000 UTF-8 bytes). The schema now bounds count and characters; the byte
limit is a card rule in both judges. Vectors: nine lines and 1001 characters
(schema), 501 two-byte characters (rule), and a card at both caps (valid).
