Add an expansion preview system so the Goddess and Vampire panels render
their full content (zones, bosses, thralls, achievements, etc.) even when the
expansion has not been unlocked, with all interactive elements visually
disabled.
- API /load now returns expansionPreview alongside game state, populated from
initialGoddessState() and initialVampireState() — never part of the saved blob
- LoadResponse type updated with expansionPreview field
- gameContext exposes goddessPreview and vampirePreview, stored in separate
state vars that never touch stateReference so saves are never polluted
- gameLayout applies expansion-preview CSS class when viewing a locked expansion
with preview data available, and shows the coming-soon banner
- All 22 expansion panels updated to use state.vampire ?? vampirePreview and
state.goddess ?? goddessPreview for display
- CSS disables all buttons/inputs/selects inside .expansion-preview
- apotheosis service patched to never auto-initialise goddess state — expansion
remains locked until explicitly released
- vampire blood production tick with thrall bloodPerSecond + multipliers
- auto-quest and auto-thrall purchase in tick engine
- computeVampireBloodPerSecond helper exposed for ResourceBar display
- ResourceBar now shows blood/s and currency balances for vampire mode
- vampire quests and thralls panels gain auto-toggle buttons
- About page updated with vampire mode how-to-play entries
- vampireEquipmentSets data file added to web
- 100% test coverage across all API routes and services:
- siring, awakening, vampireBoss, vampireCraft, vampireExplore, vampireUpgrade
- debug route now covers grant-apotheosis endpoint
- vampireMaterials excluded from coverage (ID-referenced only, same as goddessMaterials)
Implements VampireBossPanel (zone filtering, HP bar, battle modal with
rewards/casualties) and VampireThrallsPanel (batch buy with geometric
cost scaling). Wires challengeVampireBoss, dismissVampireBattle, and
buyVampireThrall into GameContext with correct sort-key ordering.
