| Dependency-free progress bar for Python. | |
| Features: | |
| - Works with a known total OR unknown total. | |
| - Prints ETA when total is known. | |
| - Throttles updates to avoid spamming stdout. | |
| - Safe for long-running loops; finalizes cleanly. |
Use OFFSET for small datasets and random-access pages. Use keyset/seek for deep paging and stability.

-- LIMIT/OFFSET vs Keyset (Seek) Pagination
--
-- OFFSET pagination is simple but can get slow on deep pages and can produce
-- duplicates/missing rows if data changes between requests.
