# Design QA

- Source visual truth: `/workspace/scratch/6e52996114b8/upload/18a4bcb0-1b3a-43c8-b459-deef213b5c2f.png`
- Source pixel dimensions: `235 × 137`.
- Intended implementation viewport: responsive dark theme; desktop shows hover explanations and mobile disables them at `760px` and below.
- Implementation screenshot: unavailable.
- CSS size and density normalization: unavailable because the implementation could not be opened in the cloud browser.
- State: 形态图片页默认筛选、网格布局、四个图标操作可见。

## Full-view comparison evidence

The source crop shows four adjacent icon buttons with two different spacing values: the grid/masonry pair is tightly grouped while refresh and batch image have visibly larger gaps.

The implementation now places all four controls in one flex group with a shared `8px` gap. Grid, masonry, refresh, and batch image each use `NPopover`; all four popovers share the same responsive `disabled` state and are disabled at `max-width: 760px`.

A local Sites preview started successfully, but the cloud browser rejected `terminal.local` with `net::ERR_BLOCKED_BY_CLIENT` on both attempts. Therefore no browser-rendered implementation screenshot is available.

## Focused region comparison evidence

- Control order: grid → masonry → refresh → batch image.
- Spacing: all four controls are direct children of the same `gallery-layout-switch` flex group with `gap: 8px`.
- Desktop explanations: all four controls use hover-triggered `NPopover` copy.
- Mobile behavior: all four popovers bind `:disabled="isMobile"`; the media query follows `(max-width: 760px)`.
- Accessibility: every icon-only button retains a stable Chinese `aria-label`; native `title` attributes were removed from the first two buttons.

These are code-level checks only and do not replace a rendered focused-region comparison.

## Required fidelity surfaces

- Fonts and typography: no visible toolbar type styles changed; popover typography remains Naive UI-managed.
- Spacing and layout rhythm: the four-button group now uses one uniform `8px` rhythm.
- Colors and visual tokens: selected and unselected button colors are unchanged.
- Image quality and asset fidelity: no image behavior changed.
- Copy and content: desktop popovers explain `网格布局`, `瀑布流布局`, `刷新图库`, and `批量生图`; mobile keeps accessible names without hover overlays.

## Findings

- [P1] Browser-rendered comparison unavailable
    - Location: 形态图片筛选区的四个图标按钮。
    - Evidence: the required cloud browser returns `net::ERR_BLOCKED_BY_CLIENT` for the healthy local preview on two attempts.
    - Impact: exact pixel spacing, popover placement, hover visibility, responsive disabling, and console state cannot be visually certified.
    - Fix: capture the page in an available browser at desktop and mobile widths and compare the four-button control group.

## Primary interactions tested

Automated tests verify the exact four-button order, layout switching, refresh behavior, four desktop popover bindings, responsive disabled binding, accessible labels, and uniform generated `8px` CSS gap. All 275 tests pass. Browser hover and touch interaction were unavailable.

## Console errors checked

Not checked because the page could not be opened in the cloud browser.

## Comparison history

- Iteration 1: the source identified inconsistent spacing and missing explanations on the first two controls.
- Iteration 2: consolidated all four controls into one spacing group, added popovers to grid and masonry, disabled all four popovers on mobile, and passed the full test/build suite. Browser capture remained blocked.

## Implementation checklist

- [x] Give all four icon buttons the same gap.
- [x] Add `NPopover` explanations to grid and masonry.
- [x] Disable all four `NPopover` components on mobile.
- [x] Preserve accessible labels and existing button behavior.
- [ ] Capture and compare desktop hover and mobile touch states in the cloud browser.

final result: blocked
