/**
 * OpenStation — Recycle Bin: tile art, gate, shell config.
 *
 * The bin WINDOW is an App Framework app (`apps/trash/trash.os.php`)
 * that claims the frozen `desktop-mode-recycle-bin` id, so every
 * shortcut, dock placement and drop target keeps working. This file
 * keeps what the shell needs regardless of the window: the two bin
 * drawings (the dock tile's empty/full swap — `icon-state.ts` — and
 * the app's own `ctx.host.setIcon()` swap read the same pair), the
 * capability gate, the shell-config seed that makes the tile correct
 * on the very first paint, and the stylesheet enqueue (the
 * drag-to-trash drop-target highlight must exist at boot, not at
 * window-open).
 *
 * @package OpenStation

/**
 * The bin SVG, used by the app window's icon and its dock tile.
 *
 * The bin used to be `dashicons-trash`, which worked but wore the
 * wrong clothes. Dashicons are WP core's icon set: solid fills on a
 * 20-unit grid, tuned for admin-menu sizes. The shell's own icons are
 * outlined vessels on a 64-unit grid at stroke 3. Sitting next to
 * WP Explorer, Corkboard and Games in the dock, the Dashicon was
 * visibly a guest from another system: heavier, tighter, and drawn to
 * a different rhythm.
 *
 * So this is the same object, redrawn to the house rule the other
 * three follow: an outlined vessel with solid content, three elements
 * because it renders as small as 20px in the dock. The lid is the
 * solid one, which gives the mark a single dense horizontal to be
 * recognised by when the tapered body below it thins out.
 *
 * Drawn in `currentColor`, so `renderIcon()` paints it as a CSS mask
 * and it takes the surface's own text colour. Dashicons already
 * inherited colour, being font glyphs; the point of the change is the
 * drawing, not the theming.
 *
 * Note that the row actions inside the bin window, and the "Move to
 * trash" entries in context menus, stay on `dashicons-trash`. Those
 * are menu glyphs sitting among other menu glyphs, and they should
 * match their neighbours rather than this icon.
 *
 * The bin has two states. Empty is the vessel on its own; full adds
 * three crumpled balls inside it and knocks the lid askew.
 *
 * @param bool $full Whether to draw the bin holding something.
 * @return string Raw `<svg>` markup.
