/**
 * The Corkboard SVG, shared by the window icon and the desktop icon.
 *
 * The thread is the window's actual subject: the links between pieces
 * of content. That reading is unchanged and is why this icon exists at
 * all. What changed is everything drawn around it.
 *
 * The previous version framed two pinned notes with the thread arcing
 * over them. On a 64-unit grid the arc closed the top of the
 * silhouette, and a closed top over two rectangles is a bag: at 40px
 * and below the icon read as a shopping bag rather than a board. The
 * frame was also spending most of the 20px budget on an outline that
 * carried no meaning, leaving the notes too small to be notes.
 *
 * So the board and the paper are gone and the graph is the whole mark:
 * one focused post with related ones fanned around it, which is what
 * the window itself draws now that nodes are discs rather than post-
 * type glyphs (see `src/content-graph/satellites.ts`). Sizes are
 * deliberately unequal, so the hierarchy reads without a caption.
 *
 * Pin-led marks are deliberately avoided: `assets/images/pushpin.svg`
 * belongs to pinned notes, and an icon led by a pin would point at
 * that feature instead of this one.
 *
 * Drawn in `currentColor`, which makes it a silhouette: `renderIcon()`
 * paints it as a CSS mask rather than a background-image, so it takes
 * whatever colour the surface is already using for text. That keeps it
 * legible on the dark dock, on a light title bar, and under a desktop
 * theme's icon tint, with nothing to configure.
 *
 * Hand-placed at 64×64 like the Games icon, the established shape for
 * custom icons here, and held to five elements because it renders as
 * small as 20px in the dock.
 *
 * @return string Raw `<svg>` markup.
