+ hint_id joins with support_card_data.skill_set_id, but it isn't unique; e.g., Seiun Sky SR has the
+ same hint_id as prior Seiun Sky cards, despite having a different hint list. Unclear what it actually does. Doesn't

+ support_card_id is effectively the lookup key.

+ hint_group ties together the results of one hint. Skill hints are generally one each, but stat hints have two or

+ hint_gain_type is 0 for skill hints and 1 for stat hints.

+ For skill hints, hint_value_1 is the skill ID, and hint_value_2 is always 1; presumably the latter could
+ serve as the base value of hint levels. For stat hints, hint_value_1 is the stat ID – 1 for speed through 5
+ for wit, or 30 for skill points – and hint_value_2 is the amount to add.
