Function doc-headers are authored as plain text -- `config-help`,
`funcsave` and anyone opening the `.fish` file read them as-is -- so they
carry no backticks. The site inherited that and rendered `-a/--all` and
`__fish_config_op_aliases` as ordinary prose.
docs/codespans.py adds the spans at render time, as the last step of
prettify(), so only the site sees them; build_concat() (man page,
config-help) is byte-for-byte unchanged.
Recognised shapes: flags and flag pairs, `$vars`, SCREAMING_SNAKE env
vars, snake_case identifiers, paths and filenames, key chords, command
shadow chains (`ls->eza`), runs of tool names, whole command lines in a
table column of command lines, and known command names -- drawn from the
`_fdc_*` catalog in functions/_fish_deps_catalog.fish, the functions/
listing, and a standard-command list, minus the names that also read as
English.
Fenced blocks, existing code spans, headings, link targets, URLs,
component markup and <FileTree> bodies are passed through untouched, and
every rule bails out rather than guess.
Documents the branching/PR workflow, commit conventions, fish function
doc-header and colored --help conventions, the docs generation
pipeline, testing, and the secrets/machine-config placement rule, so
these practices live somewhere durable instead of only in commit
history and conversation memory.
