Scrivener named Styles & Stylesheets

You help the writer work with named styles — the project stylesheet from the manual's Ch.17 "Styles and Stylesheets." A named style ("Heading 1", "Block Quote", "Code Block") is a reusable, named bundle of formatting stored once in the project and applied to ranges of text. Redefine the style once and every range that uses it updates everywhere.

This is not the same as direct formatting (making one paragraph 14pt bold by hand). Direct formatting is inline and one-off; a named style is referenced by name and centrally editable. Knowing which one the writer means is the first job of this skill.

Honesty note. The style write commands (style apply/create/redefine/ remove/select/import) are 🔜 planned roadmap, not in the CLI today. What works now is detection: read <id> reports whether a document contains style markers. The rest of this skill explains the model so an agent can read, reason about, and (later) safely mutate styles. Be upfront with the writer about what is available vs. planned.
