/* =============================================================================
   MODAL COMPONENTS - Unified Modal System
   =============================================================================

   Uses semantic tokens from themes.css for automatic theme support.
   All modals across the application use these base styles.

   USAGE:
   - Always use CSS variables from themes.css
   - Extend these base styles for specialized modals (e.g., card details modal)
   - Dark theme support is automatic through CSS variables

   THEME NOTES
   ========================================

   This file uses CSS variables from themes.css exclusively.
   Dark theme support is automatic - no body.dark-theme overrides needed!

   Variables used:
   - Surface: --modal-bg, --surface-secondary, --surface-tertiary
   - Text: --text-primary, --text-secondary, --text-tertiary, --text-inverse
   - Border: --border-primary, --border-secondary
   - Interactive: --interactive-hover, --overlay-light, --overlay-heavy
   - Shadows: --shadow-md, --shadow-lg, --shadow-xl
   - Colors: --color-primary, --color-primary-dark
   - Spacing: --spacing-xs through --spacing-2xl
   - Radius: --radius-sm through --radius-full
   - Scrollbar: --scrollbar-track, --scrollbar-thumb, --scrollbar-thumb-hover
   - Transitions: --transition-fast, --transition-base
   - Focus: --focus-ring

   To customize modals for a specific theme:
   1. Update the semantic tokens in themes.css
   2. All modals will update automatically
   3. No need for body.dark-theme overrides

   MOBILE SLIDE-UP SHEET (Phase 9)

   On mobile, any .modal using the standard .modal-content pattern is rendered
   as a bottom-anchored slide-up sheet — full width, rounded top corners only,
   small grabber visual at the top edge. This catches deck details, playtest,
   share, confirmation, import/export, and any other standard modal in the
   app in a single pass.

   The card detail modal uses its own classes (.cardModal-overlay /
   .cardModal-container) and got its sheet override in phase 2 directly in
   card-modal.css.

   Modals that opt out by setting their own align-items / position on .modal
   (e.g. specialised editor surfaces) keep working — this only overrides the
   default .modal centering layout.
   ============================================================================= */
