joshuaandClaude Opus 5.5 932e755895 V1.3.0: Hollowcrown seed, player visibility rules, initiative rolls, number limits, temp HP
- Hollowcrown: The Rift Between Worlds as its own seed (npm run
  seed:hollowcrown), built from the campaign book: pools, 58 monsters,
  57 NPCs, 28 locations, 72 encounters with rewards, and DM notes. Shared
  seeding logic moved to prisma/seedCampaign.js.
- What players can see: only encounters their own character is in; only
  the pool entries their character holds (plus starting options while
  building); only locations their character has been to; no invite code;
  no gold, inventory or money log of other players' characters. Socket
  events carry ids only and campaign rooms are members-only.
- Encounters have a location; while one is in progress its characters are
  there, and visits are remembered.
- Campaign setting to show players a health bar only for monsters and NPCs.
- Initiative is entered as the d20 roll (1-20) and the bonus is added;
  players can enter their own character's roll.
- Number fields enforce their limits when typing, and the API enforces
  the same limits.
- Temp HP shows on HP bars and absorbs damage before real HP.
- All packages at version 1.3.0.

// Temporary hit points are a buffer: damage comes off them first, and only
// what is left over reaches real HP. Takes the character's HP and temp HP as
// they are and the HP a damage/heal asked for (which may be below zero), and
// returns what both should become. Healing never touches temp HP.
