/*
 * Link hover underline, synchronised with the colour change.
 *
 * Pico draws a link as `text-decoration: var(--text-decoration)` and transitions
 * `color` and `text-decoration` over the same `var(--transition)`. Its resting
 * value is `none`, so the hover underline (a discrete line change) appears at once
 * while the colour eases in. Keeping the line present at rest but transparent
 * leaves only the decoration colour to change, which Pico's existing transition
 * animates alongside the text colour.
 *
 * Load after pico.min.css.
