class_name Weapon

## One weapon: its stats, its swing, and how it sits in the hands.
##
## Replaces MeleeAttack. The important new part is `vs` — the WEAPON vs MATERIAL
## matrix the founding doc asked for. A weapon no longer just "breaks things"; it does
## `power * vs[material]` damage against that material's toughness (Smashable.PROFILES
## .hp). That is what makes the loadout a decision instead of a skin:
##
##   box cutter  — shreds cardboard and paper, pings uselessly off a filing cabinet
##   cricket bat — the all-rounder; snaps vinyl and glass, struggles with steel
##   crowbar     — the only mid-speed answer to steel
##   sledgehammer— ends anything, but you swing it once a second
##
## Swing timing matters as much as damage: `contact` is how far into the animation the
## hit actually lands, so the sledge connects late and heavy while the cutter is instant.
##
## Godot 4.7 GDScript 2.0.
