Corrected real errors: several 1.7.x release dates, resource_pack_send version,
config packet ordering, structured-component count (56), PLAYER_LOADED (1.21.4),
entity_sound_effect field order. Confirmed+cited the rest; remaining ~19 items
re-marked UNCONFIRMED (third-party/ViaLegacy/26.2 internals unreachable from refs).

### 2.3 Packet size limits
- Uncompressed maximum: **2²¹ − 1 = 2,097,151 bytes** (the `Length` VarInt may not exceed 3 bytes on the wire). — [minecraft.wiki](https://minecraft.wiki/w/Java_Edition_protocol)
- Serverbound compressed: uncompressed (Packet ID + Data) must be ≤ 2²³ bytes (8,388,608). <!-- VERIFY: wiki states this limit; not reflected in node-minecraft-protocol source -->
- Plugin message unrecognised-channel data: vanilla client caps at 1,048,576 bytes. <!-- VERIFY -->

Source: [minecraft.wiki/w/Java_Edition_protocol/Packets](https://minecraft.wiki/w/Java_Edition_protocol/Packets) — "For serverbound packets, the uncompressed length of (Packet ID + Data) must not be greater than 2^23 or 8388608 bytes." (node-minecraft-protocol's decompressor does not enforce this cap; Velocity's `MinecraftCompressDecoder` caps serverbound at 2 MiB for security, vanilla at 8 MiB clientbound — `MinecraftCompressDecoder.java:39-40`.)
