/**
 * CDSWerx Shared Underline Engine
 *
 * Single source of truth for the animated-underline keyframes used by both the
 * CTA Button (single-line bar) and the TOC widget (multi-line, wrap-following
 * gradient). Widgets supply their own application rules but share these
 * keyframes so the motion stays in lockstep.
 *
 * - cds-animate-underline-from-left / -from-right : single-line "draw" redraw
 *   (used by the button ::after bar — scaleX based).
 * - cds-animate-underline-multiline / -multiline-thick : wrap-following draw for
 *   inline text spanning multiple lines (background-size based, used by TOC).
 *
 * @package CDSWerx_Widget_Library
 * @since   2.14.0

   Shared link/button underline reset — single source of truth.

   In CDSWerx widgets the underline is ALWAYS a pseudo-element (:after bar) or
   the wrap-following gradient — never `text-decoration`. The per-widget
   `text-decoration: none` bases are specificity (0,1,0), which theme link rules
   like `.elementor-widget-container a` (0,1,1) out-rank, so themes underline
   these labels even when the widget's underline control is Off. This !important
   reset makes the control the single source of truth for every CDSWerx
   label/link. It does NOT affect the :after / gradient underline features
   (not text-decoration), and deliberately EXCLUDES the intentional-underline
   cases (biolinks link-mode, calendar-link hover, section title-decoration) and
   line-through (pricing). Enqueued globally so it reaches every widget. */
