/* ===================================
   BUTTON COMPONENTS
   =================================== */

/*
 * BUTTON COMPONENT STRUCTURE
 *
 * This button system uses a base class (.btn) combined with variant classes and size modifiers
 * to create a flexible, consistent button interface. All buttons share common base styles while
 * variants provide semantic meaning through color and state behaviors.
 *
 * DESIGN REFERENCE:
 *   Based on sage-green-2 design specifications located at:
 *   layout/colors/sage-green-2.html
 *
 * BUTTON CLASS HIERARCHY:
 *   1. Base class: .btn (required - provides foundation styles)
 *   2. Variant class: .btn-primary, .btn-secondary, .btn-success, etc. (optional - provides color/semantics)
 *   3. Size modifier: .btn-sm, .btn-lg (optional - adjusts dimensions)
 *
 * USAGE EXAMPLES:
 *   <button class="btn btn-primary">Save Changes</button>
 *   <button class="btn btn-sm btn-secondary">Cancel</button>
 *   <button class="btn btn-lg btn-success">Confirm</button>
 *   <a class="btn btn-danger" href="/delete">Delete Item</a>
 *
 * BEST PRACTICES:
 *   - Always include the .btn base class
 *   - Use semantic variants to convey meaning, not just color
 *   - Combine size modifiers with variants for proper sizing
 *   - Buttons can be applied to <button>, <a>, and <input type="submit"> elements
 *   - Use .btn-sm for constrained spaces and .btn-lg for primary CTAs
 *
 */

/*
 * Base Button (.btn)
 *
 * The foundation class for all button variants. Provides consistent dimensions,
 * typography, and interaction behaviors that are inherited by all button types.
 *
 * PROPERTIES:
 *   - Padding: 12px 24px (comfortable touch targets)
 *   - Border-radius: 8px (soft, modern corners)
 *   - Font-size: 16px (readable base size)
 *   - Font-weight: 500 (medium weight for balance)
 *   - Transition: 0.3s ease (smooth state changes)
 *   - Display: inline-flex (proper alignment with icons)
 *
 * STATE BEHAVIORS (inherited by all variants):
 *   - Normal: Base appearance as defined by variant
 *   - Hover: Subtle lift effect (-2px translateY)
 *   - Active: Pressed effect (0px translateY) with variant-specific styling
 *   - Disabled: Managed via HTML disabled attribute (grayscale appearance)
 *
 * DESIGN NOTES:
 *   - No border on base buttons (clean, modern look)
 *   - Pointer cursor indicates interactivity
 *   - Gap: 0.3rem for spacing button text from icons

 * WHEN TO USE:
 *   - Highlighting primary or important budgets
 *   - Creating visual variety in budget lists
 *   - When a more prominent card appearance is desired
 *
 * WHEN NOT TO USE:
 *   - When solid background cards are more appropriate (use .budget-card)
 *   - In areas with multiple gradient cards to avoid visual fatigue
 *
 * DESIGN REFERENCE: sage-green.html lines 86-92
 *
 * GRADIENT: Linear gradient from var(--primary-sage) to var(--primary-light) at 135deg
 * TEXT: White color for contrast with gradient background
 *
 * DARK MODE COMPATIBILITY:
 *   - The gradient uses theme-agnostic brand colors (primary-sage, primary-light)
 *   - These colors remain the SAME in both light and dark modes
 *   - White text ensures readability across both themes
 *   - Hover state slightly darkens the gradient for visual feedback

 *     Dark theme: --bg-secondary = #1e293b (dark blue-gray)
 *
 * CONTRAST REQUIREMENTS:

 *   - Background colors use darker shades in dark mode
 *   - Border colors adjusted for visibility
 *   - Hover states provide visual feedback

    =================================== */

/*
 * WCAG 1.4.4: Resize text
 *
 * Ensures text can be resized up to 200% without breaking the layout.
 * Users with low vision often increase browser text size to improve readability.
 *
 * IMPLEMENTATION:
 *   - All text containers use relative units (rem, em, %)
 *   - Fixed pixel widths are avoided in favor of max-width
 *   - Flexbox and Grid layouts accommodate text scaling
 *   - Overflow handling prevents horizontal scrolling at 200% zoom
 *
 * WCAG REFERENCE: https://www.w3.org/WAI/WCAG21/Understanding/resize-text
 *
 * PHASE 3 COMPLETION NOTE:
 *   All form inputs, buttons, and text elements have been enhanced with
 *   focus indicators that meet WCAG 2.1 AA requirements (3:1 contrast).
 *   Color contrast has been verified for all theme colors in both
 *   light and dark modes.
