- Reject non-finite numerics at protocol parse and in the engine
(a 1e400 seek became Infinity and broke every broadcast).
- Reject empty swaps; sanitize URL-looking media names.
- Blank password = open server; defaults no longer 'change-me'.
- Loopback peers (the in-process host) can't be kicked.
- /health no longer exposes media/transport; file URLs use the
host the client dialled instead of 127.0.0.1.
- Count served bytes as streamed, not as requested.

Private-server headroom over any pipeline PNG. The 8-min
auto-unready warning now mirrors the 10-min action guard: no toast
when self isn't ready, since there's nothing to lose.
64 KiB rejected normal 128px PNGs. 128 KiB fits any 128x128 PNG
(raw <= 64 KiB, worst-case base64 ~95 KiB chars) while still
bounding abuse. PNG kept for transparency. Pipeline now measures
the encoded base64 against RelayConstants (was checking the wrong
variable with its own 512 KiB limit) and drops dead crop code.
Server policy, still v4. Trade noted: avatars ride the 1 Hz room
broadcast, uplink scales with cap; hash-reference follow-up later.
