+# Discovered Rules — Finalized
+
+> Hard constraints surfaced from the project description, the empirical
+> research, and the interview. Promoted to `memory/project.md` at the
+> affirmation gate.
+
+## Mandated
+
+- ALWAYS generate pure HTML5 + CSS with no build step and no external
+  dependencies, so the result runs entirely from the local filesystem
+  (never beyond localhost).
+- ALWAYS make the rendered page printable cleanly to A4 from the browser's
+  print dialog.
+- ALWAYS fetch or read content only through user-granted means (native file
+  picker / drag-and-drop) when the page runs from `file://` — never rely on
+  `fetch()` of sibling local files, because the opaque-origin policy blocks it
+  in stock browsers (empirically verified: plain Chromium blocks
+  `fetch('article.txt')` from a `file://` page, while the native file picker
+  works).
+- ALWAYS make the page work with zero network requests (no CDN fonts, no
+  remote `<script>`/`<style>`), so it is fully functional offline from `file://`.
+
+## Forbidden
+
+- NEVER reference content, fonts, or assets by remote URL; everything ships
+  with the page.
