/*
 * TextStrikethrough — spring-animated strikethrough line
 *
 * Draws a line-through from left to right using clip-path on a
 * transparent-text overlay that carries the text-decoration.
 * Grid stacking (grid-area: 1/1) layers the overlay on the base text.
 *
 * Key trick: -webkit-text-fill-color hides the glyph paint while
 * keeping `color` (and therefore `currentColor` / text-decoration-color)
 * set to the real inherited text color.
