"""Regression tests: MEDIA tag formatting variants that previously broke delivery.

Covers the two follow-up fixes layered on top of the salvaged contributor PRs:

1. Sentence-final punctuation — ``MEDIA:/x/data.csv.`` at the end of a
   sentence must extract ``data.csv`` (the trailing ``.`` is a boundary, not
   part of the path), while multi-part extensions (``archive.tar.gz``)
   remain intact.

2. Inline-code-wrapped tags — a whole ``MEDIA:`` tag inside inline backticks
   (`` `MEDIA:/path.csv` ``) is a real delivery directive when the path
   validates on disk; prose examples with non-existent paths stay masked
   (#35695), and fenced code blocks are always masked.
