+
+      "Object" form shall mean any form resulting from mechanical

+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# MathMax
+
+Toán tương tác cho học sinh THCS Việt Nam (lớp 6-9). Số học, Đại số, Hình học qua kéo-thả và minh hoạ trực quan.
+
+## Status
+
+Scaffold only (v0.0.1.0). Landing page liệt kê 3 chủ đề với "Sắp ra mắt". Modules tương tác sẽ ra mắt từng phần.
+
+## Develop
+
+Yêu cầu: Node 24+, npm 11+.
+
+```sh
+npm install
+npm run dev          # http://localhost:5173/mathmax/
+npm run build        # Static output → build/
+npm run preview      # Serve build/
+```
+
+## Deploy
+
+Auto-deploy lên GitHub Pages từ `main` qua `actions/deploy-pages@v4`. Xem `RUNBOOK.md` để rollback / chuyển domain.
+
+Live URL: https://tiennm99.github.io/mathmax/
+
+## Architecture
+
+- **Static**: SvelteKit + `@sveltejs/adapter-static`, `paths.base = '/mathmax'`, output `build/`.
+- **Styling**: Tailwind 3 (PostCSS), system font stack (Be Vietnam Pro sẽ thêm khi có module đầu tiên).
+- **Language**: JavaScript only (Svelte 5, JSDoc qua `jsconfig.json`).
+- **i18n**: Hiện chỉ có tiếng Việt. English thêm khi cần.
+
+## License

+# Runbook — MathMax
+
+## Deployment
+
+Production deploys from `main` via GitHub Actions (`.github/workflows/deploy.yml`).
+
+- Live URL: `https://tiennm99.github.io/mathmax/`
+- Build: `npm run build` (SvelteKit static, output to `build/`)
+- Deploy mechanism: `actions/upload-pages-artifact@v3` + `actions/deploy-pages@v4`
+- Concurrency: `pages-deploy` group, cancel-in-progress disabled (so a force-pushed retry doesn't abort an in-flight rollback)
+
+## Rollback
+
+GitHub Pages keeps the last successful deployment. To roll back:
+
+1. Find the offending commit on `main`: `git log --oneline main`
+2. Revert it: `git revert <sha>` and push to `main`
+3. The next workflow run rebuilds and re-deploys the prior good state
+4. Verify the live site
+
+If the workflow itself is broken (e.g., bad `deploy.yml` change), use the GitHub UI to re-run a previous successful deployment from the **Deployments** tab.
+
+## CI
+
+- `.github/workflows/ci.yml` runs build on every PR and push to `main`. Build failure on `main` blocks the deploy job.
+- Local equivalent: `npm install && npm run build`
+
+## Domain migration trigger
+
+Per plan, buy a `.vn` / `.com.vn` domain only when ANY of:
+
+1. **500 unique sessions** in any rolling 30-day window post-launch, OR
+2. **1 organic teacher share** (Facebook group, Zalo, or school chat — verified, not founder-initiated), OR
+3. **≥5 modules shipped** (signals content sustainability and amortizes the domain cost)
+
+If none hit within 90 days of soft launch, stay on `tiennm99.github.io/mathmax/`.
+
+When the trigger fires:
+
+1. Register the domain (VN registration: passport scan + address proof + MIC filing, 7–14 days)
+2. Add `CNAME` file at repo root with the new domain (e.g. `mathmax.vn`)
+3. Configure custom domain in GitHub Pages settings (Settings → Pages → Custom domain)
+4. Update `svelte.config.js`: change `paths.base` from `/mathmax` to `/`, update any hardcoded references. Or update the workflow `env:` block.
+5. Update OpenGraph + canonical URLs (handled automatically once `svelte.config.js` reflects the new domain)
+6. Wait 24h, then update sitemap submission in Google Search Console
+7. Set up 301 redirects (GitHub Pages handles this automatically once the custom domain is the primary)
+
+## Things to NOT do
+
+- Never `git push --force` to `main`.
+- Never edit `VERSION` or `package.json.version` independently — they must agree.
+- Never change `svelte.config.js` `paths.base` without simultaneously updating the deploy workflow `env:` and any hardcoded internal links.
+- Never run `npm install` in CI without committing the resulting `package-lock.json` locally first.
+
+## Initial CI note
+
+Initial CI uses `npm install` (no lockfile committed yet). After first successful run, user commits `package-lock.json` locally and we switch CI to `npm ci` in a follow-up PR.
