/* ---------- Icon (Lucide-style inline SVG from lib/icons.js) ----------
 * The symbol pool ships stroke-based outlines. Without these defaults the
 * browser paints each <path> with the SVG default (fill:black, stroke:none),
 * so every icon reads as a solid black blob. fill:none + stroke:currentColor
 * renders crisp line icons that inherit the surrounding text colour. Symbols
 * that need a solid fill (i-play, the i-tag dot) carry their own
 * fill="currentColor" attribute, which overrides this base.
 * NB: size comes from the width/height attributes set by icon() — do not set
 * width/height here or every icon collapses to one size. */
