# Wood Paneling Smart Font Colors Fix Plan

## Overview

Add smart font colors for wood paneling backgrounds on the dashboard. When a wood texture is applied to `#collections-container`, the text color will automatically adjust to ensure readability.

## Current State

- Textures exist: `wood-light.png`, `wood-dark.png`, `wood-mahogany.png`
- **Issue**: Current `wood-mahogany.png` is too light (should be darkest)
- **Issue**: Current `wood-dark.png` may also need replacement (verify brightness)
- Wood paneling applies background to `#collections-container`
- Text colors currently use theme CSS variables (`var(--text-primary)`, `var(--text-secondary)`)
- Problem: Theme-based text colors may not contrast well with wood textures

## Requirements

1. **Keep existing naming**: `wood-light`, `wood-dark`, `wood-mahogany` (no renaming needed)
2. **Verify texture brightness**: Mahogany must be darkest, dark is medium, light is lightest (DO NOT change wood-light)
3. **Smart font colors**: Dark wood needs light text, light wood needs dark text
4. **Scope**: All text within `#collections-container` when wood is active
5. **Fallback**: When no wood is selected, use theme colors (current behavior)

## Implementation Plan

### Step 0: Verify and Replace Mahogany Texture

The current `wood-mahogany.png` is too light and needs to be replaced with the darkest texture from the source pack. **DO NOT change `wood-light.png`.**

**Download and extract texture pack:**
```bash
cd /tmp
curl -O https://opengameart.org/sites/default/files/wood_0.zip
unzip wood_0.zip
cd wood_0
ls -la  # Should show wood1.png, wood2.png, etc.
```

**Rename extracted textures:**
```bash
# From /tmp/wood_0, copy to bookhoard textures directory
cd web/static/textures
cp /tmp/wood_0/wood1.png wood-dark.png

# wood2.png → wood-mahogany (darkest)
cp /tmp/wood_0/wood2.png wood-mahogany.png

# wood-light.png remains unchanged (keep existing file)

# Verify
ls -lh web/static/textures/
```

**Brightness validation checklist:**
- [ ] `wood-dark` (was wood1.png) is medium-dark brown
- [ ] `wood-mahogany` (was wood2.png) is the darkest, deep reddish-brown
- [ ] `wood-light` remains unchanged (lightest)

### Step 1: Update `woodPaneling.ts`

Add `data-wood` attribute to the container when applying backgrounds. This allows CSS selectors to target wood-specific styling.

**File**: `web/src/woodPaneling.ts`

**Change 1** - In `applyWoodPaneling()` function, remove wood classes and data attribute:
```typescript
// Before:
container.classList.remove('bg-wood-light', 'bg-wood-dark', 'bg-wood-mahogany');

// After:
container.classList.remove('bg-wood-light', 'bg-wood-dark', 'bg-wood-mahogany');
container.removeAttribute('data-wood');
```

**Change 2** - In `applyWoodPaneling()` function, add wood class and data attribute:
```typescript
// Before:
if (paneling !== 'none') {
    container.classList.add(`bg-${paneling}`);
}

// After:
if (paneling !== 'none') {
    container.classList.add(`bg-${paneling}`);
    container.setAttribute('data-wood', paneling);
}
```

### Step 2: Update `woodPanelingInit.ts`

Apply the same `data-wood` attribute during early initialization to prevent flash.

**File**: `web/src/woodPanelingInit.ts`

**Change** - In `applyPaneling()` function, add data-wood attribute:
```typescript
// Before:
const applyPaneling = () => {
    const container = document.getElementById('collections-container');
    if (container) {
        container.classList.add(`bg-${woodPaneling}`);
    }
};

// After:
const applyPaneling = () => {
    const container = document.getElementById('collections-container');
    if (container) {
        container.classList.add(`bg-${woodPaneling}`);
        container.setAttribute('data-wood', woodPaneling);
    }
};
```

### Step 3: Add Smart Font Color CSS

Add CSS variables and selectors for each wood type in `input.css`.

**File**: `web/static/input.css`

**Add to `@layer components` section** - Add after the `.bg-wood-inactive` rule (around line 207-208), before the closing `}` of @layer components:

```css
/* Smart text colors for wood paneling backgrounds */
/* Wood Light - needs dark text for contrast */
#collections-container[data-wood="wood-light"] {
    --wood-text-primary: #1a1a1a;
    --wood-text-secondary: #4a4a4a;
    --wood-border: #2a2a2a;
}

/* Wood Dark - needs medium text */
#collections-container[data-wood="wood-dark"] {
    --wood-text-primary: #d0d0d0;
    --wood-text-secondary: #a0a0a0;
    --wood-border: #5a4a3a;
}

/* Wood Mahogany - needs light text (darkest background) */
#collections-container[data-wood="wood-mahogany"] {
    --wood-text-primary: #f5f5f5;
    --wood-text-secondary: #c0c0c0;
    --wood-border: #5c3317;
}

/* Apply wood-specific text colors to all text within collections container */
#collections-container[data-wood] h1,
#collections-container[data-wood] h2,
#collections-container[data-wood] h3,
#collections-container[data-wood] p,
#collections-container[data-wood] span,
#collections-container[data-wood] a,
#collections-container[data-wood] button {
    color: var(--wood-text-primary) !important;
}

#collections-container[data-wood] .text-sm,
#collections-container[data-wood] .text-secondary,
#collections-container[data-wood] p.text-sm {
    color: var(--wood-text-secondary) !important;
}

/* Preserve accent color for links */
#collections-container[data-wood] a[style*="accent"] {
    color: var(--accent) !important;
}

/* Add subtle borders to book cards on wood backgrounds */
#collections-container[data-wood] .book-card {
    border: 1px solid var(--wood-border);
}
```

### Step 4: Build and Verify

Run build commands to verify changes compile correctly.

```bash
# Build CSS first (regenerates style.css with new utilities)
npm run build:css

# Then build TypeScript
npm run build:ts

# Verify Go templates compile
go build ./...
```

## Files Modified

| File | Changes |
|------|---------|
| `web/static/textures/wood-dark.png` | Rename from extracted wood1.png |
| `web/static/textures/wood-mahogany.png` | Rename from extracted wood2.png |
| `web/static/textures/wood-light.png` | **DO NOT CHANGE** |

## Testing Checklist

### Texture Verification
- [ ] Mahogany is visibly the darkest of all three textures
- [ ] Wood-dark is medium brightness
- [ ] Wood-light is lightest (unchanged)
- [ ] All textures are PNG format

### Font Color Testing

- [ ] `wood-light` shows dark text (#1a1a1a)
- [ ] `wood-dark` shows light text (#d0d0d0)  
- [ ] `wood-mahogany` shows light text (#f5f5f5)
- [ ] "None" option uses theme colors (no `data-wood` attribute)
- [ ] Book cards have subtle borders on wood backgrounds
- [ ] "View All" links preserve accent color
- [ ] No console errors

## Wood Brightness Reference

| Source File | Target File | Brightness | Text Color |
|------------|-------------|------------|------------|
| `wood-light.png` | `wood-light.png` | Lightest | Dark (#1a1a1a) | **DO NOT CHANGE** |
| `wood1.png` | `wood-dark.png` | Medium | Medium (#d0d0d0) |
| `wood2.png` | `wood-mahogany.png` | **Darkest** | Light (#f5f5f5) |

## Notes

- The `data-wood` attribute is only present when a wood option is selected
- Absence of `data-wood` attribute means theme colors apply (no breaking change)
- CSS `!important` is used to override theme CSS variables within the selector scope
- Book card borders help separate content from wood texture
