DPYLogger: leveled discord channel logger (debug/info/success/fail/task/
critical) over discord.py. config-free — embed identity injected at
construction, per-guild channel routing read live from bot.settings.
dual-sink: mirrors every call to the stdlib logger. embed_builder
callable + build_embed override for customization. raises by design;
object-only (no module proxy). src/ layout, hatchling build.
