/**
 * FLOSC App Layout (v1.4.6) — Ultra Pro Edition
 * ==============================================
 * Updated: 2026-02m-06d
 * 
 * LAYOUT ONLY — No colors, no theme styles.
 * All visual styling comes from flosc-theme.css + chat-style-*.css presets.
 * 
 * ARCHITECTURE:
 * 1. flosc-layout.css  — Structure, positioning, flexbox (this file)
 * 2. flosc-theme.css   — Variable consumption, theming
 * 3. chat-style-*.css  — Variable definitions (light/dark/claude/chatgpt/grok)
 * 
 * BACKWARD COMPATIBILITY:
 * Supports both legacy class names and new flosc- prefixed names.
 * Legacy selectors are grouped with new selectors using CSS commas.
 * 
 * ============================================================================
 * ⚠️  HARD-LEARNED LESSON: SVG ICON VISIBILITY (2026-01m-25d)
 * ============================================================================
 * AI tools repeatedly broke icon visibility by adding incorrect CSS rules.
 * After 6+ failed AI attempts and hours of debugging, here's what works:
 * 
 * THE PATTERN THAT WORKS:
 * ┌─────────────────────────────────────────────────────────────────────────┐
 * │  HTML (in flosc-app.php):                                               │
 * │  <button class="my-button">                                             │
 * │      <svg fill="none" stroke="currentColor" stroke-width="2">          │
 * │          <path d="..."></path>                                          │
 * │      </svg>                                                              │
 * │  </button>                                                               │
 * ├─────────────────────────────────────────────────────────────────────────┤
 * │  CSS Layout (this file):                                                │
 * │  .my-button { display: flex; align-items: center; ... }                 │
 * │  .my-button svg { width: 20px; height: 20px; display: block; }          │
 * ├─────────────────────────────────────────────────────────────────────────┤
 * │  CSS Theme (flosc-theme.css):                                           │
 * │  .my-button { color: var(--some-color); }  -- EXPLICIT color --        │
 * │  .my-button:hover { color: var(--hover-color); }                        │
 * └─────────────────────────────────────────────────────────────────────────┘
 * 
 * WHY THIS WORKS:
 * - stroke="currentColor" makes SVG inherit color from parent element
 * - Parent button MUST have explicit color (not inherit/initial/unset)
 * - display: block on SVG prevents inline whitespace issues
 * - Hover on button changes color, SVG automatically updates
 * 
 * WHAT BREAKS IT (AI kept doing these):
 * ✗ Adding stroke: currentColor in CSS (already in HTML, causes specificity wars)
 * ✗ Using fill instead of stroke for line-art icons
 * ✗ Omitting color on button and relying on inheritance
 * ✗ Adding !important everywhere (masks the real problem)
 * ✗ Inline styles to "fix" visibility (breaks theming)
 *
