++ # R24 (skill-language-style): alt text starts with a capital letter and has
++ # no trailing period.
++ #
++ # NOTE: styles/Qt/Structure/QDocImageAltInlineCmd.yml uses `scope:
++ # text.comment.image.alt`, which looked like the right scope to reuse for
++ # alt-text *content* rules (as opposed to that rule's own inline-command
++ # check). Empirically it never fires -- not even on
++ # tests/QDocImageAlt.qdoc's own "SHOULD WARN" fixture lines under the
++ # installed Vale 3.21.0 build (see styles/Qt/Structure/README.md) -- so this rule
++ # is written against scope: raw instead, matching the QDoc source directly.
++ # A single alternation with (?m): see the test report for why a
++ # multi-entry raw list and an unanchored $ don't work in this Vale build.
