+/* Fixed full-bleed layer behind all content. Renders a chafa output of the
+   og-image-bg.svg (black background + "tui-pages" wordmark + headline +
+   subtitle), drawn as ASCII glyphs in a single full-width tile. Two copies
+   of the tile are stacked vertically and the whole track drifts slowly
+   upward, looping seamlessly when the top copy exits the viewport.
+
+   The hero is a static <img src="static/img/terminal-default.svg"> as
+   designed - this file does NOT touch the hero.
+
+   Regenerate the source tile with `make ascii` (uses chafa on
+   static/img/og-image-bg.svg). The chafa output is in static/ascii/rain.txt
+   and is 240 columns wide. */
