DoxBackpack

### Short description

**Grid-based backpacks** — a Tarkov-style inventory where every item occupies a **w×h footprint** and you arrange gear in a grid. Six backpack sizes (small → giant) open a grid you drag items into; oversized items need space to fit. Item footprints are **extensible via DoxCore**: other mods register their own item sizes, so ammo, magazines, healing items, etc. size correctly when those mods are present. If **TACZ** is installed, guns are auto-sized per gun; if **DoxPartHealth** is installed, a part-health bar overlays the backpack screen. Works standalone — unknown items default to 1×1.

### Features

- **Grid inventory** with per-item w×h footprints; 6 backpack tiers (2×3 → 5×8).

- **Extensible item sizes** — `DoxCore.DoxItemSize` registry; producer mods register their items' sizes (soft, addon-style).

- **TACZ gun sizing** (optional) — pistols/SMGs/rifles/snipers/LMGs sized per gun id.

- **Part-health overlay** (optional, DoxPartHealth) in the backpack screen.

- **Refit** and mirrored-container flows; server-authoritative grid with client sync.

### Requirements

- **DoxCore** (required). DoxPartHealth / TACZ optional (enhance when present; nothing breaks when absent).

### For modders

- `DoxCore.api.DoxItemSize.register(predicate, w, h, stackable)` — declare your item's backpack footprint.
