Related to #58.

align() prepends a tab to the message; it does not pad the level. With simple(), different level lengths can reach different tab stops. This documents that limitation and adds an executable padLevels() + simple() example using the existing API. The explanation covers custom levels, the raw LEVEL symbol, finalizer ordering, fixed-width prefixes and the limitation of string-length padding for Unicode terminal cells.

Runtime behavior is unchanged. This does not claim to fix the output of align() + simple() or resolve every alignment layout. Nine characterization/composition tests cover the documented behavior and recipe, including metadata and colorized output. Custom color registrations are restored after each test.

Validation at head 3319427:

• Windows / Node 24.19.0: npm test (including lint/build), 178 passing; TypeScript check passed. The actual README snippet was executed.
• Linux / Node 22, 24 and 26: npm test, 178 passing on each, versus 169 on the unchanged baseline. Test-name inventories contain all baseline cases plus the nine additions. TypeScript checks passed.
• The combine/colorize files also pass in both orders, 30 tests per order. Existing lint warnings are unchanged (16, zero errors).
