- Implement server-side location chaining with HTMX support via `htmx=True` in fields and widgets. - Update location views to handle HTMX requests and return HTML <option> fragments. - Add NepaliDateYearFilter and NepaliDateRangeFilter for robust DRF API filtering. - Expand default `DATE_INPUT_FORMATS` in configuration to support multiple common Nepali date styles. - Update DRF serializers to automatically respect global `NEPKIT` configuration settings. - Add `django-filter` as an optional dependency under the `drf` extra in pyproject.toml. - Correct underlying dependency references from `nepali-datetime` to nepali library. - Complete overhaul of README.md for premium DX, including new sections for storage behavior, timezone awareness, and API usage.
