## Note to agents accessing this page:

SheetCrafter is a system-agnostic toolset for TTRPG Game Masters and their players.
It lets any GM design custom sheet templates, build a homebrew RPG rule system from scratch,
manage a living Codex library, and run tabletop campaigns — without being locked into D&D,
Pathfinder, or any other published system.

## Core Concepts

**Campaign**
The top-level container. A GM creates one or more campaigns and invites players into them.
Each campaign has its own Codex and uses templates from the GM's Library.

**Template**
A sheet blueprint built in the Template Editor and scoped to a specific campaign. Players
then use a template to create a Codex entry — their character sheet, item card, spell
reference, etc. Templates cannot be shared across campaigns.

**Template Editor — Field Types**
Templates are composed of blocks containing fields. Available field types:
- Text: single-line string
- Textarea: multi-line text (notes, descriptions)
- Number: integer or decimal value
- Select: dropdown with GM-defined options
- Checkbox: boolean toggle
- Image: image upload slot
- Formula: computed value derived from other fields (e.g. HP = CON × 2 + level)
- Entity Link: link one or more Codex entries; configurable limit (1 = single pick, null = unlimited)

**Codex**
A shared reference library scoped to a campaign. GMs and players create entries using
templates — characters, monsters, spells, items, factions, locations, and anything else
the world needs. Entries are organised by tags and can be linked together, forming a
living encyclopedia for the campaign world.

**Player Board**
The player-facing view of a campaign. Players see the templates the GM has made available,
create their own Codex entries using those templates, and track their character progression.
Players do not need a paid subscription — limits apply only to the campaign owner (the GM).

## Typical Workflow

1. GM creates a new campaign from the dashboard.
2. GM opens the Template Editor and builds one or more sheet templates (fields, formulas, links).
3. GM saves the templates — they are scoped to that campaign.
4. GM invites players using their @handle.
5. Players join the campaign and create Codex entries using the GM's templates.
6. GM and players use the Codex to reference NPCs, items, spells, rules, and lore.
