-# CSS Modules Guide for AI Agents
-
-## Config (vite.config.ts)
-
-```ts
-css: {
-  modules: {
-    localsConvention: 'camelCaseOnly',
-  },
-}
-```
-
-**Critical:** `camelCaseOnly` exports ONLY camelCase keys. Original kebab-case NOT accessible.
-
-## Quick Reference
-
-| CSS Class | JS Access | Works? |
-|-----------|-----------|--------|
-| `.alertHistory` | `styles.alertHistory` | Yes |
-| `.alert-history` | `styles.alertHistory` | Yes |
-| `.alert-history` | `styles['alert-history']` | NO - undefined |
-
-## Bad Patterns
-
-### Class Naming
-
-```scss
-// BAD: Bracket access won't work
-.my-class { }
-// Then in JS: styles['my-class'] -> undefined
-
-// BAD: Collision - both become same key
-.alertHistory { }
-.alert-history { }  // -> styles.alertHistory (conflicts)
-
-// BAD: Underscore inconsistency
-.my_class { }  // -> styles.myClass (confusing)
-
-// GOOD: Direct camelCase
-.alertHistory { }
-.statsCard { }
-```
-
-### Nesting
-
-```scss
-// BAD: Deep nesting - specificity wars, hard to override
-.container {
-  .wrapper {
-    .inner {
-      .content { }
-    }
-  }
-}
-
-// BAD: Nesting creates separate classes you might not expect
-.button {
-  .icon { }  // -> styles.icon (separate class, not scoped under .button)
-}
-
-// GOOD: Flat structure
-.container { }
-.containerWrapper { }
-.containerContent { }
-
-// GOOD: Nesting only for pseudo/states
-.button {
-  &:hover { }
-  &:disabled { }
-  &::before { }
-}
-```
-
-### Global Escapes
-
-```scss
-// BAD: Overusing global
-:global {
-  .everything { }
-  .in-here { }
-  .is-global { }
-}
-
-// BAD: Global without necessity
-:global(.myComponent) { }  // defeats purpose of modules
-
-// GOOD: Targeted global for third-party overrides
-.container {
-  :global(.ant-modal-content) {
-    padding: 0;
-  }
-}
-```
-
-### Selectors
-
-```scss
-// BAD: ID selectors - not reusable
-#myComponent { }
-
-// BAD: Element selectors without scope
-div { }  // affects ALL divs in component
-
-// BAD: Complex selectors
-.container > div + span ~ p { }
-
-// GOOD: Class-only selectors
-.container { }
-.title { }
-```
-
-### Variables & Values
-
-```scss
-// BAD: Hardcoded colors
-.button {
-  background: #1890ff;
-  color: white;
-}
-
-// BAD: Magic numbers
-.container {
-  padding: 17px;
-  margin-left: 43px;
-}
-
-// GOOD: Semantic tokens (theme-aware)
-.button {
-  background: var(--primary-background);
-  color: var(--primary-foreground);
-}
-
-.card {
-  background: var(--l2-background);
-  color: var(--l2-foreground);
-}
-
-// GOOD: Spacing system
-.container {
-  padding: var(--spacing-4);
-  margin-left: var(--spacing-5);
-}
-```
-
-## Design Tokens (@signozhq/design-tokens)
-
-Prefer semantic tokens over hardcoded values.
-
-You can read the ./node_modules/@signozhq/design-tokens/dist/style.css to find complete list of available tokens.
-
-### Spacing
-
-```scss
-// Spacing scale (index -> px):
-// --spacing-0=0    --spacing-1=2    --spacing-2=4    --spacing-3=6    --spacing-4=8
-// --spacing-5=10   --spacing-6=12   --spacing-7=14   --spacing-8=16   --spacing-10=20
-// --spacing-12=24  --spacing-16=32  --spacing-20=40  --spacing-24=48  --spacing-32=64
-// --spacing-40=80  --spacing-48=96  --spacing-56=112 --spacing-64=128
-// (index != px; --spacing-2 is 4px, not 2px)
-.container {
-  padding: var(--spacing-4);      // 8px
-  gap: var(--spacing-6);          // 12px
-  margin-bottom: var(--spacing-8); // 16px
-}
-
-// Also available: --padding-* and --margin-* (rem-based)
-// --padding-1 = 0.25rem, --padding-4 = 1rem, etc.
-```
-
-### Typography
-
-```scss
-// Font sizes (preferred)
-.title {
-  font-size: var(--periscope-font-size-large);   // 18px
-  font-size: var(--periscope-font-size-medium);  // 16px
-  font-size: var(--periscope-font-size-base);    // 13px
-  font-size: var(--periscope-font-size-small);   // 11px
-}
-
-// Alternative scale (rem-based)
-.heading {
-  font-size: var(--font-size-xl);  // 1.25rem
-  font-size: var(--font-size-lg);  // 1.125rem
-  font-size: var(--font-size-base); // 1rem
-  font-size: var(--font-size-sm);  // 0.875rem
-}
-
-// Font weights
-.bold {
-  font-weight: var(--font-weight-semibold); // 600
-  font-weight: var(--font-weight-medium);   // 500
-  font-weight: var(--font-weight-normal);   // 400
-}
-
-// Line heights
-.text {
-  line-height: var(--line-height-20); // 20px
-  line-height: var(--line-height-24); // 24px
-}
-```
-
-### Colors (Prefer Semantic Tokens)
-
-Use L1/L2/L3 semantic tokens - they handle light/dark theme automatically.
-
-```scss
-// BAD: Primitive tokens (fixed value across themes, won't swap on theme change)
-.card {
-  background: var(--bg-ink-400);
-  color: var(--text-vanilla-100);
-}
-
-// GOOD: L1/L2/L3 tokens (theme-aware - swap automatically light/dark)
-.card {
-  background: var(--l1-background);  // base layer
-  color: var(--l1-foreground);       // primary text
-}
-
-.panel {
-  background: var(--l2-background);  // elevated surface
-  color: var(--l2-foreground);       // secondary text
-  border-color: var(--l2-border);
-}
-
-.nested {
-  background: var(--l3-background);  // nested/inset
-  color: var(--l3-foreground);       // tertiary text
-}
-
-// Hover states
-.card:hover {
-  background: var(--l1-background-hover);
-  color: var(--l1-foreground-hover);
-}
-
-// Semantic action colors (also theme-aware)
-.primary {
-  background: var(--primary-background);
-  color: var(--primary-foreground);
-}
-
-.danger {
-  background: var(--danger-background);
-  color: var(--danger-foreground);
-}
-
-.success {
-  background: var(--success-background);
-  color: var(--success-foreground);
-}
-
-.warning {
-  background: var(--warning-background);
-  color: var(--warning-foreground);
-}
-
-// Accent colors (for highlights, badges, etc.)
-.accent {
-  background: var(--accent-primary);        // robin blue
-  background: var(--accent-forest);         // green
-  background: var(--accent-cherry);         // red
-  background: var(--accent-amber);          // yellow
-}
-```
-
-**Token hierarchy:**
-- Primitive tokens (`--bg-*`, `--text-*`, etc.) have fixed values across themes.
-- Semantic tokens (L1/L2/L3, `--primary-*`, `--danger-*`, etc.) automatically swap based on theme.
-- L1 = base/root layer
-- L2 = elevated surfaces (cards, panels)
-- L3 = nested/inset elements
-
-## Overriding @signozhq/ui Components
-
-Components expose CSS variables for customization.
-
-You can ensure they exist by looking at ./node_modules/@signozhq/ui/dist.
-Never write a override without confirm it exists.
-
-Override via:
-
-### Method 1: CSS Variables (Preferred)
-
-Each component exposes `--<component>-<property>` variables:
-
-```scss
-// Override Button
-.customButton {
-  --button-background: var(--success-background);
-  --button-border-radius: var(--radius-2);
-  --button-padding: var(--spacing-4) var(--spacing-8);
-  --button-font-size: var(--periscope-font-size-base);
-}
-
-// Override Input
-.customInput {
-  --input-height: 2.5rem;
-  --input-border-color: var(--l2-border);
-  --input-padding: var(--spacing-2) var(--spacing-6);
-  --input-placeholder-color: var(--l3-foreground);
-}
-
-// Override nested parts
-.customInput {
-  --input-prefix-padding: 0 var(--spacing-4) 0 var(--spacing-6);
-  --input-suffix-color: var(--accent-primary);
-}
-```
-
-### Method 2: Data Attributes
-
-Components use data attributes for variants/states. Target them for state-specific overrides:
-
-```scss
-// Target variant
-.wrapper :global([data-variant="outlined"]) {
-  --button-border-color: var(--accent-primary);
-}
-
-// Target size
-.wrapper :global([data-size="sm"]) {
-  --button-font-size: var(--periscope-font-size-small);
-}
-
-// Target color
-.wrapper :global([data-color="destructive"]) {
-  --button-background: var(--danger-background);
-}
-
-// Target state (Radix patterns)
-.popover :global([data-state="open"]) {
-  opacity: 1;
-}
-
-.tooltip :global([data-side="top"]) {
-  margin-bottom: var(--spacing-2);
-}
-```
-
-### Common Component CSS Variables
-
-**Button:**
-- `--button-background`, `--button-border-radius`, `--button-padding`
-- `--button-font-size`, `--button-height`, `--button-gap`
-- `--button-hover-background`, `--button-disabled-opacity`
-
-**Input:**
-- `--input-height`, `--input-border-color`, `--input-background`
-- `--input-padding`, `--input-font-size`, `--input-placeholder-color`
-- `--input-focus-outline-color`, `--input-hover-border-color`
-- `--input-prefix-*`, `--input-suffix-*` for adornments
-
-**General pattern:** `--<component>-<property>` or `--<component>-<state>-<property>`
-
-## Good Patterns
-
-### Structure
-
-```scss
-// Flat, descriptive, component-scoped
-.alertHistory { }
-.alertHistoryHeader { }
-.alertHistoryContent { }
-.alertHistoryFooter { }
-
-// State modifiers as separate classes
-.alertHistory { }
-.alertHistoryLoading { }
-.alertHistoryEmpty { }
-.alertHistoryError { }
-```
-
-### Composition
-
-```scss
-// GOOD: Composing styles
-.baseButton {
-  padding: var(--spacing-2) var(--spacing-4);
-  border-radius: var(--radius-2);
-}
-
-.primaryButton {
-  composes: baseButton;
-  background: var(--primary-background);
-}
-```
-
-### Pseudo Elements
-
-```scss
-.button {
-  // States
-  &:hover { opacity: 0.9; }
-  &:focus { outline: 2px solid var(--ring); outline-offset: 2px; }
-  &:disabled { opacity: 0.5; cursor: not-allowed; }
-
-  // Pseudo elements
-  &::before { content: ''; }
-  &::after { content: ''; }
-}
-```
-
-### Media Queries
-
-```scss
-.container {
-  display: flex;
-  flex-direction: column;
-  
-  @media (min-width: 768px) {
-    flex-direction: row;
-  }
-}
-```
-
-## JS Import Patterns
-
-```tsx
-// GOOD
-import styles from './Component.module.scss';
-
-<div className={styles.container}>
-  <span className={styles.title}>Title</span>
-</div>
-
-// GOOD: Conditional classes
-<div className={`${styles.button} ${isActive ? styles.buttonActive : ''}`}>
-
-// GOOD: With clsx/classnames
-<div className={clsx(styles.button, { [styles.buttonActive]: isActive })}>
-
-// BAD: Bracket access (may be undefined)
-<div className={styles['button-active']}>  // undefined if CSS has .button-active
-
-// BAD: String interpolation for class names
-<div className={`${styles.button}-active`}>  // won't work
-```
-
-## Checklist Before Committing
-
-- [ ] All class names use camelCase in CSS
-- [ ] No bracket access (`styles['...']`) in JS unless verified
-- [ ] No deep class nesting (max 3 class levels; pseudo-classes/elements and parent-reference selectors like `&.active`, `&#bar` are not counted)
-- [ ] No hardcoded colors - use `--l1/l2/l3-*` semantic tokens (not `--bg-*` primitives)
-- [ ] No magic numbers - use `--spacing-*` tokens
-- [ ] Typography uses `--periscope-font-size-*` or `--font-size-*` tokens
-- [ ] @signozhq/ui overrides use CSS variables, not direct class overrides
-- [ ] Global escapes only for third-party overrides
-- [ ] No ID selectors
-- [ ] No bare element selectors
