…ML Templates ## Summary Implements the public Server-Side Rendered (SSR) Release Notes page (`GET /release-notes/<int:milestone>` and `GET /release-notes`) using hyphenated URL paths to match existing `developer.chrome.com/release-notes` URL conventions. Provides fast initial load time, zero JS bundle dependencies, search engine SEO indexing, public CDN caching (`HTTP_CACHE_TYPE = 'public'`), a Symmetrical Navigation Strip (Channel Quick-Jumps + Milestone Combobox Selector), M151 cutoff HTTP 302 redirect handling, and responsive category-grouped feature cards styled via native `main.css` design tokens. ## Key Changes - **Controller (`pages/releasenotes.py` & `main.py`)**: Implements `ReleaseNotesHandler(basehandlers.FlaskHandler)` with `HTTP_CACHE_TYPE = 'public'` registered under `/release-notes/<int:milestone>` and `/release-notes`. Assembles template context with channel milestone mappings (`stable`, `beta`, `dev`), M151 cutoff redirect (`MIN_SSR_RELEASE_NOTES_MILESTONE = 151`), and category-grouped features. - **Template (`templates/release-notes.html`)**: Extends `_base.html`. Implements the Symmetrical Navigation Strip, native `main.css` button classes, hyphenated `/release-notes/` href links, and responsive Flexbox feature cards. - **Testing (`pages/releasenotes_test.py` & Playwright)**: Added 16 Python unit tests covering public cache configuration, M151 cutoff HTTP 302 redirects, parameter resolution, and a modular Playwright test suite (`packages/playwright/tests/chromedash-release-notes-ssr_pwtest.js`).
