Add tooling/render-pack.sh: renders all pack/**/*.tmpl with ${BASE_DOMAIN}
(no dnsmasq HOST_LAN_IP coupling) and rebuilds the packwiz index. Both
render-config.sh and add-custom-mod.sh now delegate to it.
CustomSkinLoader.json's skin API roots are no longer frozen — it becomes
CustomSkinLoader.json.tmpl, rendered like the mod metadata. .packwizignore
broadened to *.tmpl; rendered .json gitignored as build output.

Ulicraft modpack (packwiz)
This directory is the single source of truth for the modpack (MC 1.21.1, NeoForge 21.1.209). Curate mods from here with packwiz modrinth add <slug> (prefer Modrinth over CurseForge); each mod produces a mods/<slug>.pw.toml metadata file referencing the upstream CDN. Client-only mods must be tagged side = "client" in their .pw.toml so the itzg server does not pull and crash on them. After adding/removing mods run packwiz refresh to recompute index.toml; for offline LAN play run tooling/mirror-mods.sh to vendor the jars and rewrite the download URLs to the local Caddy mirror. Curation is an ongoing manual task — no mods are added yet.
