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.
embed_builder callable + build_embed override for customization. raises
by design; object-only (no module proxy). src/ layout, hatchling build.

+discord channel logger
+
+leveled logging to a discord channel via embeds. attach to your bot
+(e.g. bot.log) and call bot.log.info(...), bot.log.critical(...), etc.
+
+config-free: all static identity is injected at construction; dynamic
+per-guild channel routing is read live from bot.settings at call time, so a
+command that mutates bot.settings changes routing without a restart.
+
+    from dpy_logger import DPYLogger
+
+    bot.log = DPYLogger(
+        bot, guild_id, channel_id,
+        colors=cfg.log_colors,        # optional, falls back to defaults
+        pings=cfg.authorized_devs,    # mentioned on critical()
+        timezone=cfg.timezone,
+        footer=cfg.bot_footer,
+        avatar=cfg.bot_avatar,
+    )
+    await bot.log.initialize()        # resolves ids -> objects
+    await bot.log.success("user promoted", action="promote", actor=ctx.author)
+
+levels: debug, info, success, fail (alias failure), task, critical.
+
+dynamic routing: a per-call guild= argument logs to that guild's configured
+channel via bot.settings[guild.id]['channels']['logs']; omit it to use the
+channel this logger was constructed with.
+
+custom embeds: pass embed_builder=fn to restyle without subclassing, where
+fn(logger, level, action, actor, details) -> discord.Embed. every level
+(including critical) routes through it. for complex cases override the
+build_embed method in a subclass instead.
+
+extending: this base has no feed/announcement method by design. a project
+that wants one subclasses DPYLogger and adds it, reusing _resolve.
+
+errors: unlike the swallow-and-return-default libs, this one raises. guild and
+channel resolution raise ValueError when a target can't be resolved, and send
+failures propagate — a logger that can't reach its channel should fail loudly
+rather than silently drop the record. callers logging from a command handler
+should account for that (e.g. wrap non-critical logging if a failed log must
+not break the command).
