Dark Mode Check

• Set via S.Common.setThemeClass() in src/ts/store/common.ts
• Applied by U.Common.addBodyClass('theme', 'dark') in src/ts/lib/util/common.ts
• Values: 'dark', 'light', 'system' (system defers to nativeThemeIsDark)

CSS Variable System

Light mode defaults: src/scss/_vars.scss Dark mode overrides: src/scss/theme/dark/common.scss (lines 5-82)

Core variable families:

Dark Mode File Organization

src/scss/theme/dark/
├── common.scss    (~485 lines) - CSS variables + shared overrides + icon paths
├── page.scss      (~236 lines) - Page-specific dark styles
├── block.scss     (~250 lines) - Block component dark styles
├── menu.scss      (~315 lines) - Menu dark styles
├── popup.scss     (~116 lines) - Popup/modal dark styles
└── widget.scss    (~87 lines)  - Widget dark styles

All are imported via src/scss/common.scss.

Icon Theming

Dark mode icons live in src/img/theme/dark/ mirroring src/img/icon/:

$themePath: '~img/theme/dark';

html.themeDark {
    .icon.buttonAdd { background-image: url('#{$themePath}/icon/block/add0.svg'); }
    .icon.buttonAdd:hover { background-image: url('#{$themePath}/icon/block/add1.svg'); }
}

Convention: name0.svg = default, name1.svg = hover/active.

In TypeScript, dynamic icon paths use S.Common.getThemePath():

// Returns 'theme/dark/' or ''
const path = `./img/${S.Common.getThemePath()}icon/file/${type}.svg`;

Dark Shadow Mixin

// In dark/common.scss
@mixin shadow {
    box-shadow: 0px 4px 16px rgb(0 0 0 / 20%), 0px 0px 0px 1px #393933 inset;
}

Review Checklist

When auditing a file or component for dark mode correctness, check every item below.

1. Hardcoded Colors

Rule: No raw hex (#xxx), rgb(), or rgba() values should appear in dark mode blocks unless they are truly one-off (e.g., a specific gradient stop with no variable equivalent).

Search pattern:

grep -E '#[0-9a-fA-F]{3,8}|rgb\(|rgba\(' src/scss/theme/dark/*.scss

Known violations (for reference):

• src/scss/theme/dark/block.scss — .label { color: #464646; }, bgColor-* classes with hardcoded hex
• src/scss/theme/dark/common.scss — shadow mixin #393933, vault #393939, iconWrap #4f4f4f/#000000, markup highlight #044062
• src/scss/theme/dark/menu.scss — bgColor-* palette, .connected::before #294b0e, .error::before #581f0c
• src/scss/theme/dark/page.scss — .btn.light .bg { background-color: #fff; }

Action: Flag each hardcoded color. Suggest the closest CSS variable or recommend creating a new one.

2. Inline Dark Overrides Outside Theme Folder

Rule: Dark mode style overrides belong in src/scss/theme/dark/. They should NOT be placed inline in component SCSS files using html.themeDark & or html.themeDark .component.

Search pattern:

grep -rn 'html\.themeDark\|\.themeDark' src/scss/ --include='*.scss' | grep -v 'src/scss/theme/dark/'

Known violations:

• src/scss/popup/aiOnboarding.scss — Lines 69-91, inline html.themeDark & block with hardcoded rgba() colors
• src/scss/form/button.scss — Dark mode button overrides
• src/scss/page/main/settings.scss — Dark mode settings overrides

Action: Flag inline dark overrides. Recommend moving them to the appropriate file in src/scss/theme/dark/.

3. Missing Icon Dark Variants

Rule: Every icon that appears in the UI must have a dark variant in src/img/theme/dark/ if its default color doesn't work on dark backgrounds.

Check process:

1. Find all .icon.* classes that set background-image in light mode SCSS
2. Verify each has a corresponding entry in src/scss/theme/dark/common.scss or other dark theme files
3. Verify the SVG file exists in src/img/theme/dark/icon/

Search patterns:

# Find icon background-image declarations in light mode
grep -rn 'background-image.*icon/' src/scss/ --include='*.scss' | grep -v 'theme/dark'

# Find dark mode icon overrides
grep -rn 'background-image.*themePath' src/scss/theme/dark/

Action: For each icon missing a dark variant, flag it and check whether the default icon color (typically #B6B6B6 or #252525) needs adjustment for dark backgrounds.

4. Dynamic Icon Paths in TypeScript

Rule: Any TypeScript code building icon paths must use S.Common.getThemePath() for theme awareness.

Search pattern:

grep -rn "img/icon/" src/ts/ --include='*.tsx' --include='*.ts' | grep -v 'getThemePath'

Action: Flag any hardcoded icon paths that bypass theme detection.

5. New CSS Properties Without Variable Usage

Rule: When adding new color/background/border properties, always use CSS variables from _vars.scss (which get overridden in dark mode). Never introduce raw color values.

Colors that MUST use variables:

• color -> use --color-text-*
• background / background-color -> use --color-bg-* or --color-shape-*
• border-color -> use --color-shape-*
• box-shadow -> use variables or the @include shadow mixin in dark mode

6. !important Overuse

Rule: Avoid !important in dark mode overrides. If needed, it usually signals a specificity problem that should be fixed by adjusting selectors.

Search pattern:

grep -cn '!important' src/scss/theme/dark/*.scss

Action: Flag excessive !important usage. Suggest selector specificity fixes.

7. Missing Dark Mode Handling for New Components

When reviewing a new component, verify:

1. All color properties use CSS variables (auto-handled by dark mode)
2. Any custom colors have corresponding overrides in src/scss/theme/dark/
3. Icons have dark variants if needed
4. Shadows use the dark mode mixin or variables
5. No opacity hacks that look wrong on dark backgrounds
6. Borders use --color-shape-* variables
7. Hover/active states work visually on dark backgrounds
