The session also recorded launch evidence, verified the package-level build and link checks, and documented the remaining deferred items for later launch phases. *** ## Deliverables ### Files Created | File | Purpose | Lines | | --------------------------------------------------------------------------------------------------- | --------------------------------------------------------------- | ------ | | `public-website/src/assets/showcase/heroes-banner-preview.webp` | Smaller launch derivative for the high-byte hero showcase asset | binary | | `.spec_system/specs/phase16-session02-performance-and-image-optimization/IMPLEMENTATION_SUMMARY.md` | Session closeout summary and handoff record | \~90 | ### Files Modified | File | Changes | | ----------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- | | `public-website/src/lib/media.ts` | Refined media metadata, loading priority, fallback links, and launch-risk notes. | | `public-website/src/components/media/OptimizedMedia.astro` | Tuned generated widths, sizes, quality, loading behavior, and reduced-motion fallback handling. | | `public-website/src/components/marketing/HeroCockpit.astro` | Tightened eager first-viewport media handling and decorative cost. | | `public-website/src/components/marketing/PressAssetGrid.astro` | Capped preview widths and documented high-byte showcase behavior. | | `public-website/src/data/company.ts` | Clarified press asset descriptors and launch-blocker copy. | | `public-website/src/styles/global.css` | Reduced expensive global motion and decorative effects. | | `public-website/src/components/navigation/MobileNavigation.astro` | Reviewed and tightened the mobile menu script lifecycle. | | `public-website/src/components/navigation/SkipLink.astro` | Kept skip-link behavior lightweight and static-safe. | | `public-website/public/press/README.md` | Documented the pass-through policy for press assets. | | `public-website/README_public-website.md` | Added performance, font, and asset-policy notes for launch handoff. | | `.spec_system/state.json` | Marked the session complete and updated session history. | | `.spec_system/PRD/phase_16/PRD_phase_16.md` | Updated the phase tracker to show session 02 as complete. | | `.spec_system/PRD/PRD.md` | Noted that Phase 16 is in progress and has two completed sessions. | | `package.json` | Bumped the root patch version from `0.1.113` to `0.1.114`. | | `README.md` | Updated the top-level version badge to match the new patch release. | *** ## Technical Decisions 1. **Keep the site static**: preserved the Astro static-output model instead of adding runtime behavior or a server adapter. 2. **Optimize through existing media plumbing**: kept image handling centered on the current registry and optimized media component rather than introducing a new pipeline. 3. **Document, do not overclaim**: recorded deferred items and launch blockers explicitly instead of broadening the launch claims. *** ## Test Results | Metric | Value | | -------- | ----- | | Tests | 4 | | Passed | 4 | | Coverage | N/A | *** ## Lessons Learned 1. Large launch assets should be tracked with both source and built-output size notes. 2. Reduced-motion fallbacks need to be validated alongside the primary visual path. *** ## Future Considerations Items for future sessions: 1. Finish the remaining Phase 16 launch-handoff sessions. 2. Revisit any deferred font or media delivery tradeoffs if launch scope expands. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 2 * **Files Modified**: 14 * **Tests Added**: 0 * **Blockers**: 0 resolved --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase16-session02-performance-and-image-optimization/implementation_summary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
