Previous value: -"Which 5e24 creation list to read. 'class' / 'species' / 'background' / 'feat' return the option projections (the user's own + stock content they may pick, with each option's nested choices — skillChoices, toolChoices, startingEquipmentOptions, and per applied ability/feat: proficiencyChoices {types,count,options}, spellChoices {count,options,prepared}, spellListChoices {categories,picks[].optionsByCategory,prepared}, preparedSpells {count} (a block's `prepared: true` = its spells land always-prepared and are EXCLUDED from the preparedSpellPicks pool), abilityScoreBump {options[].lines[]:{amount,count,eligible,max}} (supply the player's pick via `vault_build_pc.abilityBumpPicks`), and `choice` {count,options} where each option carries a `type`. The spellChoices / spellListChoices arrays are INDEX-ALIGNED with the authored blocks — a null entry holds the position of a block that grants nothing at level 1; skip it when rendering but count it when keying picks.

For a `languages.choose` grant, supply the picks via `vault_build_pc.languageChoicePicks` keyed by that rule's `_id`; `languages.fixed` apply automatically). 'feat' returns EVERY feat (the background slot uses Origin-category feats; a feat picked via an ability's `choice` may be any) — a picked feat carries its own proficiency/spell sub-choices.
