What this mod does

• Adds server-side armor weight for vanilla sets: chainmail/iron (-10% speed & jump, +2% fall damage), diamond (-20%, +5%), netherite (-25%, +5%), gold (-40%, +5%).
• Effects only apply when wearing a full matching set; partial or mixed gear stays vanilla, and spectators are ignored.
• Movement slowdown and lower jumps are handled in-server without touching client FOV.
• Fall damage is scaled up per armor weight when the full-set condition is met.

Implementation notes

• Movement input is scaled in the player travel routine and jump velocity is reduced after jumps to avoid attribute/FOV changes.
• Fall damage is increased in computeFallDamage only for players that pass the full-set check.
• Only vanilla materials listed above are weighted; other armor types and elytra are untouched.

Limitations / future ideas

• Swim/climb/elytra motion also respects the slowdown multiplier; adjust logic if you want those excluded.
• Mixed or partial armor sets never apply weight; add custom mappings if you want modded gear included.
