# Game design (vision) **Master index:** [`overview.md`](overview.md) — summary, artifact table, and links to related docs. **Progression (gigs + skills):** [`progression.md`](progression.md) — shared vocabulary and hybrid rationale. **Brainstorm-only** (not specs): [`brainstorm/`](brainstorm/README.md). Non-implementation notes: **gigs** (combat roles), **skills** (non-combat), **[abilities](abilities.md)** (what players trigger), **[items](items.md)** (loot, craft, equip), zones, mechanics, and other design artifacts before they are tied to concrete systems or tickets. Implementation-facing breakdowns stay under [`docs/decomposition/`](../decomposition/README.md) and plans under [`docs/plans/`](../plans/).
