/* ==========================================================================
   Layer Declarations
   ========================================================================== */

/*
   Cascade layers ensure predictable specificity. Layers are applied in order:

   1. reset     — Browser resets + box-sizing normalization (in this file)
   2. wpglobal  — WordPress global styles (auto-wrapped via functions.php for cascade control)
   3. base      — Global element defaults (in this file)
   4. tokens    — Design system tokens via CSS custom properties (in this file)
   5. header    — Header/navigation styles (see assets/css/header.css)
   6. components — Reusable component styles (see styles/blocks/core/*.css)
   7. utilities — Helper & utility classes (in this file)
   8. overrides — High-specificity client overrides (add your custom CSS here)

   Note: reset, base, tokens, and utilities are defined in this file.
   wpglobal layer wraps WP's global-styles-inline-css to make it overridable by other layers.
   header styles live in assets/css/header.css (enqueued via functions.php).
   Block-specific CSS lives in styles/blocks/core/ (auto-enqueued via functions.php).
*/

/* Layer order is also declared early in functions.php (wp_head priority 1) to ensure
   wpglobal is positioned correctly before WordPress outputs global-styles-inline-css.
   If you change this order, update functions.php to match.

   wpglobal is the @layer wrapper for WP's global-styles-inline-css (see functions.php
   wp_print_styles hook). Because it's named and positioned early, any layer declared
   after it (base → overrides) can override WP layout rules — including .is-layout-flow
   blockGap margins — without !important. */

/*
   QUICK REFERENCE — CSS Custom Properties (All Sources)
   ================================================

   COLOR PALETTE (from theme.json)
   —— Preset colors (use in blocks):
   --wp--preset--color--{primary, accent, secondary, base, contrast, subtle, muted}

   —— Derived states (hover, active, subtle, alpha scales):
   --color-{primary,accent,secondary}-hover           (lighten +15%)
   --color-{primary,accent,secondary}-active          (darken -15%)
   --color-{primary,accent}-subtle                    (light tint, 50% alpha)
   --color-{primary,accent,base,contrast}-alpha-{10,20,50,80}  (transparency scales)

   —— Status colors (contextual messages):
   --color-{success,warning,error,info}              (main color)

   --wp--custom--z-index--overlay  (250 — overlays)
   --wp--custom--z-index--modal    (300 — modals)
   --wp--custom--z-index--toast    (400 — notifications)

   TRANSITIONS (from theme.json — use timing + easing separately for flexibility)
   --wp--custom--transition--fast  (150ms ease — shorthand, use for simple transitions)
   --wp--custom--transition--normal (300ms ease — shorthand, use for simple transitions)
   --wp--custom--transition--slow  (500ms ease — shorthand, use for simple transitions)

   TIMING (compose with easing for complex multi-property transitions)
   --wp--custom--timing--fast      (150ms)
   --wp--custom--timing--normal    (300ms)
   --wp--custom--timing--slow      (500ms)

   EASING (use with timing for granular control)
   --wp--custom--easing--standard  (ease — standard, smooth)
   --wp--custom--easing--in        (ease-in — slow start)
   --wp--custom--easing--out       (ease-out — slow end)
   --wp--custom--easing--inOut     (cubic-bezier custom — smooth both ends)

   TYPOGRAPHY (from theme.json)
   --wp--preset--font-family--{heading, body}
   --wp--preset--font-size--{small, medium, large, x-large, 2x-large, 3x-large, 4x-large}
   --wp--custom--line-height--{tight, normal, relaxed}
   --wp--custom--letter-spacing--{tight, normal, wide}

   SPACING (from theme.json, increments 10–100)
   --wp--preset--spacing--{10, 20, 30, 40, 50, 60, 70, 80, 90, 100}

   SHADOWS (from theme.json)
   --wp--preset--shadow--{sm, md, lg, xl, inner}

   BORDER RADIUS (from theme.json)
   --wp--preset--border--radius--{small, medium, large, full}

   LAYOUT (from theme.json)
   --wp--style--global--content-size  (800px — main content width)
   --wp--style--global--wide-size     (1200px — wide section width)

   Note: WordPress preset variables are auto-generated from theme.json.
   Custom theme variables (--wp--custom--*) are defined in theme.json settings.custom.
