   WORD OF WISDOM — DEFERRED STYLESHEET (lazy-style.css)
   ==========================================================================

   Non-critical styles loaded after the initial paint to avoid blocking
   the critical rendering path. All content here is purely decorative:
   scrollbars, hover states, transitions, animations, and glassmorphism.

   Companion to style.css. Always load via the preload/onload pattern,
   never as a standard blocking <link rel="stylesheet">.

   Contents:
     §2.2  Panel Scrollbars
     §3.4  Custom Select Dropdown (moved from style.css — elements built by lazy-script.js)
           §3.4.1  Container & Hidden Native Select
           §3.4.2  Trigger Button & Arrow (base + hover)
           §3.4.3  Dropdown Panel
           §3.4.4  Options List
           §3.4.5  Scrollbar Styling
           §3.4.6  States & Animations
     §4.0  Keyframe Definitions
     §4.1  Glassmorphism Utility Class
     §4.2  Verse Interactions
     §4.3  Button Animations
     §6.0  Deferred Transitions, Hover States & Glassmorphism
