Three classes of drift cleaned up across 85 .md files:
- Em-dashes: replaced ` — ` with the contextually correct separator
(colon for `term: explanation`, period to split clauses across
sentences/source lines, parentheses for asides, semicolon for
tight-linked continuations). Two intentional exceptions remain
in `docs/contributing/documentation.md` (the rule literal) and
inside a fenced ```sh block in `docs/contributing/actions/debugging/ci.md`.
- SPOT self-labels: rewrote "This is the SPOT for X" to describe
the subject directly ("This directory holds X" / "This file
describes X"). Cross-references to other artefacts' canonical
role remain unchanged.
- Heading-emoji position: moved leading-emoji headings (`# 🧩 Title`)
to trailing position (`# Title 🧩`) per the headline rule that
emojis MUST come after the title text.

Route pushes through scripts/git/sign-push.sh so the operator's GPG key
stays outside the sandbox. Script signs only @{u}..HEAD (or merge-base
with origin/main|master on first push), skips re-signing when all
commits already carry a good signature, and uses --force-with-lease on
rewritten history. settings.json denies git push*, git send-pack*, and
make sign-push* so the agent cannot trigger a push path directly.
CLAUDE.md instructs the agent to hand off to the operator instead.
