* perf: add Brotli compression via shrink-ray-current - Replace compression middleware with shrink-ray-current for Brotli support - Remove compression and @types/compression dependencies - Add pnpm.onlyBuiltDependencies for native build deps (iltorb, node-zopfli-es) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: add negaposi-analyzer-ja to onlyBuiltDependencies The negaposi-analyzer-ja package downloads its dictionary file (pn_ja.dic.json) via a postinstall script. Without listing it in pnpm.onlyBuiltDependencies, the script is blocked and the build fails with a missing module error. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: remove node-zopfli-es from onlyBuiltDependencies node-zopfli-es fails to build with node-gyp on Node 24 (both CI and local). It is only used for zopfli compression by shrink-ray-current and is not required for Brotli. Removing it from the allowlist lets pnpm skip its broken native build.

fix: add SubmissionError guard for search form validation on React 19 redux-form 8.x relies on UNSAFE_componentWillReceiveProps for initial syncErrors hydration. React 19's batching changes prevent this from firing on mount when initialValues are provided, leaving the store without syncErrors and allowing invalid submissions to bypass validation. Adding explicit validate + SubmissionError in onSubmit ensures the error message is displayed even when redux-form's internal sync validation pipeline is not triggered.

…26) shrink-ray-current depends on iltorb, a deprecated native Brotli module that fails to build with node-gyp on Linux (Docker). Replace it with the compression middleware which uses Node.js built-in zlib and requires no native compilation. Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
fix: make AuthModalContainer static import to prevent sign-in dialog timeout
AuthModalContainer was lazy-loaded with <Suspense fallback={null}>, which meant
the <dialog> element didn't exist in the DOM until the chunk finished loading.
When the sign-in button (using Invoker Commands API: command="show-modal") was
clicked before the chunk loaded, nothing happened — causing E2E test timeouts.

fix: use inline style for dynamic background color in UserProfileHeader
Tailwind CSS cannot detect dynamically generated class names like
`bg-[${averageColor}]` at build time, so the average color extracted
from the profile image was never applied (header stayed white instead
of the expected color). Switch to an inline `style` attribute to
ensure the computed color is rendered correctly.

perf: defer modal chunk loading to reduce TBT variability AuthModalContainer and NewPostModalContainer were loaded via React.lazy() + Suspense on every page, causing their chunk parse/eval to sometimes fall within the FCP→TTI measurement window and inflate TBT scores unpredictably (0–30 range). Replace with DeferredModal component that: - Renders a lightweight placeholder <dialog> immediately (preserving commandfor compat) - Loads the actual chunk via requestIdleCallback (outside measurement window) - Falls back to toggle-event-driven loading if user interacts before idle load completes Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use 2-phase query for search API to fix pagination with subQuery: false subQuery: false causes LIMIT to apply after JOIN expansion, so posts with multiple images consume multiple rows. Split into Phase 1 (ID-only query without images JOIN) and Phase 2 (full data fetch by IDs). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: sort search results by createdAt DESC to match original behavior The original search code sorted results by createdAt DESC. The 2-phase query fix needs to preserve this ordering since defaultScope uses id DESC (UUIDs don't correlate with creation time).

All image components now request appropriately sized images (686px for post images, 80-256px for profile images) instead of full-resolution originals. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: use nearLossless WebP and skip resize for color-extracted profile image - UserProfileHeader uses FastAverageColor on the profile image, so resizing changes the extracted color and breaks VRT.
