# TokNext visual reimplementation verification

Baseline commit: `34feffc8b9d0d996e7d6da30b8a082af2a2c6db4`

## Scope and preserved behavior

- Replaced the authenticated dashboard-overview and product-detail visual layer with the supplied React/CSS hierarchy.
- Kept the existing Next.js routes, Auth.js session, Prisma queries, localization context, save mutation, billing links, and product filters/data flow.
- Rendered current database/account values; no production metric from the reference was copied into the application.
- Kept unavailable product media truthful with the existing empty-image state. The active catalog contains no usable product image URL.
- Preserved the mobile drawer and existing route behavior while removing document-level horizontal overflow.

## Final measured geometry

Dashboard at 1536x1024:

- sidebar: 272px
- content: x 300, y 30, width 1208px
- KPI row: y 128, height 179px
- main grid: y 330, height 679px
- main grid ratio: `1.7fr / 0.93fr`
- right panels: 390px growth chart and 273px categories card

Product detail at 1500x900:

- sidebar: 250px
- product layout: x 281, y 82, width 1188px
- image stage: 394x490px
- score card: x 699, y 200, width 770px, height 242px
- summary card: x 699, y 458, width 770px, height 101px
- performance card: x 699, y 573, width 770px, height 293px

Responsive width checks:

- 1440x900: no document-level horizontal overflow on either route
- 1920x1080: no document-level horizontal overflow on either route
- 390x844: `scrollWidth === innerWidth === 390` on both routes

## Behavioral verification

- All eight production captures returned HTTP 200 with no browser console errors.
- Notification button opened the real recent-activity menu.
- Account avatar opened the real account menu.
- Product detail initially selected 7D and switching to 30D updated `aria-pressed`.
- Save toggled to Saved and back; the database saved-product count was unchanged after verification.
- Both catalog navigation labels point to the real product catalog, while only Products owns the active state.

## Automated validation

- `npm run lint`: passed
- `npm test`: 39 test files and 302 tests passed
- `npx tsc --noEmit`: passed
- `npx prisma validate`: passed
- `npx prisma migrate status`: 9 migrations found, database schema up to date
- `npm run build`: passed with Next.js 16.2.11
- `git diff --check`: passed

## Visual evidence

The evidence directory includes authenticated before/after captures for both routes at 1440x900, 1920x1080, and 390x844, plus the approved fixture sizes (1536x1024 dashboard and 1500x900 product detail). It also includes overlay, absolute-difference, and side-by-side images for the two approved fixture sizes.

Mean absolute per-channel difference against the approved fixtures:

- dashboard: 16.08 / 255
- product detail: 15.35 / 255

The remaining high-difference regions are expected data-integration differences: live text and values, the real paid-account footer, real chart series, and empty media where the database has no image. Page boundaries, primary card geometry, navigation hierarchy, and first-viewport composition align with the supplied targets.

## Deployment recommendation

No deployment was performed. The implementation is ready for the user's review; deployment should remain a separate explicit action.
