Introduced `{% partialdef %}` and `{% partial %}` template tags to
define and render reusable named fragments within a template file.
Partials can also be accessed using the `template_name#partial_name`
syntax via `get_template()`, `render()`, `{% include %}`, and other
template-loading tools.
Adjusted `get_template()` behavior to support partial resolution, with
appropriate error handling for invalid names and edge cases. Introduced
`PartialTemplate` to encapsulate partial rendering behavior.
Includes tests and internal refactors to support partial context
binding, exception reporting, and tag validation.

This work amends the code from f2f6046c0f92ff1faed057da0711ac478eef439c
where multiple geometry widgets rendered `<script>` elements in the
admin with the same HTML `id`, resulting in invalid HTML and fragile
JavaScript selectors. Refs #25706.
This change uses the widget's textarea ID to generate a unique `id` for
each JSON options `<script>`, ensuring valid and robust markup.

This allows the proper resolving of lookups when performing constraint
validation involving Q and Case objects.
Thanks Andrew Roberts for the report and Sarah for the tests and review.
Regression in 849f8307a5bb33465252d0891a9b2c47dde65889.
In order to prevent underlines on links styled like buttons, role="button" was added.
This has been removed and the style updated to reflect that these are links.
Refactored `center` template filter to match f-string behaviour,
producing consistent padding for both odd and even fillings.
Thanks Lily Acorn for the report and Natalia Bidart for the review.

The section on manual testing, including how to use a local checkout of
Django, is moved from the contribution intro to the submitting patches
docs. This makes it easier for reviewers and authors to follow best
practices.
- Changed EmailMessage.message() to construct a "modern email API"
email.message.EmailMessage and added policy keyword arg.
- Added support for modern MIMEPart objects in EmailMessage.attach()
(and EmailMessage constructor, EmailMessage.attachments list).
- Updated SMTP EmailBackend to use modern email.policy.SMTP.
Deprecated:
- Attaching MIMEBase objects (replace with MIMEPart)
- BadHeaderError (modern email uses ValueError)
- SafeMIMEText, SafeMIMEMultipart (unnecessary for modern email)
- django.core.mail.forbid_multi_line_headers()
(undocumented, but exposed via `__all__` and in wide use)
- django.core.mail.message.sanitize_address()
(undocumented, but in wide use)
Removed without deprecation (all undocumented):
- EmailMessage.mixed_subtype
- EmailMultiAlternatives.alternative_subtype
- Support for setting (undocumented) EmailMessage.encoding property
to a legacy email.charset.Charset object
Related changes:
- Dropped tests for incorrect RFC 2047 encoding of non-ASCII email
address localparts. This is specifically prohibited by RFC 2047, and
not supported by any known MTA or email client. (Python still
mis-applies encoded-word to non-ASCII localparts, but it is a bug that
may be fixed in the future.)
- Added tests that try to discourage using Python's legacy email APIs
in future updates to django.core.mail.
EmailMessage is intended to support lazy strings in any header field
(via coercion to `str` in forbid_multi_line_headers() called from
SafeMIMEMessage/Text/Multipart.__setitem__).
Set flake8 max-doc-length to 79 to enforce smaller line length limit
on docstrings and comments (per coding-style docs).
Updated docs to clarify both requirements are enforced by flake8 and
to remove some leftover language from the pre-black era.
