**Status:** ✅ COMPLETE  
**Date:** December 31, 2025  
**Effort:** ~45 minutes  
**Risk:** Low

## Changes Made

### 1. PrimaryButton Polish

**File:** `packages/noodl-core-ui/src/components/inputs/PrimaryButton/PrimaryButton.module.scss`

**Visual Improvements:**

- ✅ Added rounded corners: `border-radius: var(--radius-md)` (6px)
- ✅ Applied spacing tokens for padding: `var(--spacing-button-padding-y/x)`
- ✅ Added gap token for icon spacing: `var(--spacing-button-gap)`
- ✅ Enhanced transitions (background, color, border, shadow, transform)
- ✅ CTA variant now has subtle shadow: `box-shadow: var(--shadow-sm)`
- ✅ Hover state lifts button: `transform: translateY(-1px)` + increased shadow
- ✅ Active state depresses button: `transform: translateY(0)` + no shadow
- ✅ Added accessibility focus ring: `outline: 2px solid var(--theme-color-focus-ring)`
- ✅ Improved disabled state: 50% opacity, no transform/shadow

**Typography Updates:**

- Font size: `var(--font-size-base)` (12px)
- Font weight: `var(--font-weight-medium)` (500)
- Line height: `var(--line-height-tight)` (1.2)

**Transition Timing:**

- Background/color/border/shadow: 150ms with ease curve
- Transform: 100ms for snappier feel

### 2. TextInput Polish

**File:** `packages/noodl-core-ui/src/components/inputs/TextInput/TextInput.module.scss`

**Visual Improvements:**

- ✅ Added visible border: `border: 1px solid var(--theme-color-border-default)`
- ✅ Added rounded corners: `border-radius: var(--radius-default)` (4px)
- ✅ Applied spacing tokens: `var(--spacing-input-padding-y/x)`
- ✅ Added hover state: Stronger border color on hover
- ✅ Added focus state: Red ring with `box-shadow: 0 0 0 2px rgba(210, 31, 60, 0.15)`
- ✅ Enhanced transitions for background, border, and shadow
- ✅ Focus changes border to `var(--theme-color-focus-ring)`

**Behavior:**

- Hover effect only applies when not focused or readonly
- Focus state includes both border color change AND shadow glow
- Smooth 150ms transitions throughout

## Visual Comparison

### PrimaryButton (CTA Variant)

| State    | Before              | After                               |
| -------- | ------------------- | ----------------------------------- |
| Default  | Flat, sharp corners | Rounded (6px), subtle shadow        |
| Hover    | Color change only   | Brightens, lifts 1px, larger shadow |
| Active   | Color change only   | Darkens, returns to base position   |
| Focus    | No indicator        | Red outline ring (2px)              |
| Disabled | Unclear state       | 50% opacity, obviously disabled     |

### TextInput

| State    | Before                     | After                              |
| -------- | -------------------------- | ---------------------------------- |
| Default  | Background only, no border | Border + background, rounded (4px) |
| Hover    | Slight bg change           | Stronger border color              |
| Focus    | Background change          | Red border + red glow shadow       |
| Disabled | Muted colors               | (Already handled well)             |

## Token Usage

All changes leverage the design token system:

**From TASK-000E (Spacing):**

```css
--spacing-button-padding-y: 8px
--spacing-button-padding-x: 12px
--spacing-button-gap: 8px
--spacing-input-padding-y: 6px
--spacing-input-padding-x: 8px
--radius-default: 4px
--radius-md: 6px
--shadow-sm: 0 1px 2px 0 rgba(0, 0, 0, 0.05)
--shadow-default: 0 1px 3px 0 rgba(0, 0, 0, 0.1), ...
--transition-fast: 100ms
--transition-default: 150ms
--transition-ease: cubic-bezier(0.4, 0, 0.2, 1)
```

**From TASK-000E (Typography):**

```css
--font-size-base: 12px
--font-weight-medium: 500
--line-height-tight: 1.2
```

**From TASK-000A (Colors):**

```css
--theme-color-primary
--theme-color-primary-highlight
--theme-color-primary-dim
--theme-color-focus-ring
--theme-color-border-default
--theme-color-border-strong
--theme-color-on-primary
```

## Testing Performed

### Manual Verification

✅ Buttons have rounded corners  
✅ Buttons lift on hover (CTA variant)  
✅ Buttons depress on click  
✅ Focus ring appears on keyboard navigation  
✅ Disabled buttons are clearly disabled (50% opacity)  
✅ Inputs have visible borders  
✅ Inputs show red glow on focus  
✅ Input borders strengthen on hover  
✅ All transitions are smooth (not jarring)  
✅ No visual regressions

### Variants Tested

- PrimaryButton: CTA, muted, muted-on-low-bg, ghost, danger
- TextInput: default, in-modal, opaque-on-hover, transparent variants

---

## Accessibility Improvements

1. **Focus Rings:** All buttons now have clear 2px red outline rings on focus-visible
2. **Clear Disabled State:** 50% opacity makes disabled state unambiguous
3. **Focus State Clarity:** Inputs have both border color AND shadow changes
4. **Keyboard Navigation:** Focus indicators work with tab navigation

---

## Performance Notes

- Transitions use GPU-accelerated properties (transform, opacity)
- Transform uses translate rather than margin for better performance
- All transitions use the optimized `cubic-bezier(0.4, 0, 0.2, 1)` curve
- No layout thrashing (border/padding changes are within existing bounds)

---

## Future Work (Not in Scope)

**Phase 3 Components (Deferred):**

- Select/Dropdown: Would benefit from similar treatment
- Checkbox: Checked state could use red background + rounded corners
- TextArea: Same improvements as TextInput
- Slider: Modern track styling with tokens

These can be tackled in TASK-000G or as follow-up work.

## Success Criteria

✅ Buttons feel modern and responsive  
✅ Inputs have clear, accessible focus states  
✅ All interactive states are smooth  
✅ Disabled states are obvious  
✅ Consistent use of tokens throughout  
✅ No visual regressions from previous functionality  
✅ All variants preserved and enhanced

## Developer Notes

**Why these specific changes?**

1. **Rounded corners:** Industry standard for modern UIs, feels less harsh
2. **Hover lift effect:** Provides tactile feedback, feels responsive
3. **Active depression:** Completes the button "press" metaphor
4. **Focus rings:** Critical for accessibility and keyboard navigation
5. **Input borders:** Makes fields clearly identifiable as interactive
6. **Focus glow:** Draws attention without being jarring

**Design philosophy:**

- Subtle, not flashy
- Consistent with design tokens
- Accessibility first
- Performance conscious
- Backwards compatible

## Storybook Verification

To verify these changes in Storybook:

```bash
npm run storybook
```

Navigate to:

- **Inputs / PrimaryButton** - Test all variants (CTA, muted, ghost, danger)
- **Inputs / TextInput** - Test all variants (default, in-modal, etc.)

Check:

- Hover states feel snappy and smooth
- Focus rings appear on tab navigation
- Disabled states are clearly disabled
- No jarring or stuttering animations
