…vels) Add loguru dep and a new TPTBox/logger/_loguru_backend.py: each Log_Type maps to a custom TPTBOX_* Loguru level whose color markup reproduces the exact ANSI of type2bcolors (light-cyan->96, bg blue->44, ...). print_to_terminal now emits via a colorized Loguru function-sink (writing to the live sys.stdout, honoring end so end='\r' progress lines are intact). WARNING_THROW still routes to warnings.warn. Public API/classes/verbose semantics unchanged. Verified: 28/28 golden cases render identically (only invisible reset-code differences) and all 15 non-default Log_Types emit the exact expected color code.

…on/retention) Logger now writes via a Loguru file sink instead of raw file.write. Default keeps its own handle behind a Loguru function-sink (flush() works, 'end' honored, ANSI-free, atexit-safe duration line). New rotation=/retention=/enqueue kwargs switch to a Loguru-owned path sink for rotation & retention. Per-instance record filtering keeps multiple Loggers' files isolated. Verified: exact filename scheme + header/duration lines, no ANSI in files, rotation produces multiple files, two-logger isolation, and the duration line is still written at interpreter exit for unclosed loggers.

…r sinks print_error now also emits a structured Loguru record (opt(exception=True), bound to an 'exception' channel the default sinks ignore) so user sinks capture the traceback; the human-readable text output is unchanged. Add install_excepthook() to route uncaught exceptions through Loguru (opt-in). Re-export configure, install_excepthook, and the configured loguru_logger from TPTBox.logger so callers can attach their own sinks (JSON via serialize=True, level filtering on TPTBOX_*). Configure now runs eagerly at import so the take-over logger.remove() only drops Loguru's own default handler and never wipes user sinks added afterwards.

Add unit_tests/test_logger.py (10 tests) asserting the backwards-compat contract: per-Log_Type terminal coloring matches type2bcolors, carriage-return end preserved, WARNING_THROW->warnings.warn, verbose gating, ANSI-free + isolated file output, and structured exception capture into user sinks. Document the Loguru backend, TPTBOX_* levels, take-over opt-out, rotation/retention, user sinks, and exception capture in the logger README. Full unit suite: 405 passed / 4 skipped; thread safety verified (3200 concurrent lines, no interleaving). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
