 - Per-plugin variants (code-focused, deep-technical, etc.) — would belong in a future v1.1 if there's real demand
 - Forcing the style on other plugins — it remains opt-in. Other plugins may reference it in their READMEs.
 - Translation of the style file itself into Norwegian — defeats the purpose of language-agnostic instruction

-### Linking to local files
-
-When pointing to local files in responses, always use markdown link syntax with a descriptive name:
-
-- Use `[Human-friendly name](file:///absolute/path)` — never bare `file:///...` URLs or autolinks `<file://...>`.
-- Always use absolute paths. Never `~/` or relative paths.
-- For multiple files, render as a bullet list of named markdown links.
-
-Why: bare `file://` URLs only render the first as clickable across multiple lines. Named markdown links make each entry independently clickable and look cleaner.
-
-Example:
-
-- [Brief](file:///Users/ktg/.../brief.html)
-- [Research summary](file:///Users/ktg/.../research/summary.md)
