/* Interlink icon set — consumption rules.
 *
 * Icons are monochrome and inherit their colour: `stroke="currentColor"` on the strokes and
 * `fill="currentColor"` on the solids, so an icon is always the colour of the text it sits
 * beside and re-themes with everything else. Never recolour one with --il-signal: the signal
 * marks a connection Interlink has established, and an icon is not a connection.
 *
 * Preferred: inline the SVG (it themes, and it can carry a <title>).
 * Otherwise:  <svg class="il-icon"><use href="sprite.svg#il-network"/></svg>
