// Static system-prompt blocks, loaded from `server/prompts/system/*.md`
// at module init. These are app-owned constants (model-read English,
// never user-visible, never edited at runtime), so a synchronous read
// at import time is correct — no async plumbing, no per-request I/O.
//
// Content is returned verbatim (NO trimEnd): the source `.md` files
// are byte-identical to the template literals these replaced, including
// whether or not they end in a trailing newline. `buildSystemPrompt`
// must produce a byte-identical system prompt before/after this
// refactor — see plans/done/refactor-prompts-to-files.md.
//
// Path is resolved relative to this module (import.meta.url), NOT
// process.cwd(), so it resolves under both the dev server and the
// npx-installed launcher (which ships the whole `server/` tree).
