22. SYNOPSIS
3- Fetch fresh tested Tor bridges from the Tor-Bridges-Collector GitHub repo
4- and write them to data\bridges.txt for launcher.ps1 .
3+ Fetch fresh tested Tor bridges and write a complete portable torrc NEXT TO
4+ tor.exe (template + UseBridges + Bridge lines), plus data\bridges.txt.

66. DESCRIPTION
7- Sources (default repo Delta-Kronecker/Tor-Bridges-Collector):
7+ Bridge sources (default repo Delta-Kronecker/Tor-Bridges-Collector):
88 bridge\obfs4_tested.txt -> obfs4 bridges
99 bridge\webtunnel_tested.txt -> webtunnel bridges
1010 bridge\vanilla_tested.txt -> plain (vanilla) bridges
1111
1212 Non-routable / documentation addresses (e.g. 2001:db8::/32, RFC1918,
13- TEST-NET) are filtered out, so placeholders never end up in bridges.txt.
13+ TEST-NET) are filtered out.
14+
15+ The resulting torrc sits next to tor.exe and uses only relative paths, so
16+ the whole folder is fully portable - no %APPDATA%, no absolute paths.
