+**Braille spark.** It pairs with "Stay hyped". Seven braille bars (`⣀⣤⣶⣿`) show seven days of social mentions, with today in rose. The mention count sits beside it, with its noun from `sparkCount`, so one mention reads "1 mention". On the site, a day with no mentions draws the lowest bar at 40% opacity as a track, so a lone bar still reads as one day of seven. Plain text keeps the blank cell.

 - **The braille spark replaces the trending flame**: seven braille bars for seven days of mentions, today in rose. The emoji exception for Trending is retired. The spark keeps the sourced mention count beside it, which the flame never carried. Confirmed 2026-10-06.
 - **Run and install read as different materials**: run is a dashed border with a hollow dot, because nothing stays; install is a solid border with a filled dot, because files land. Run is preselected. Confirmed 2026-10-06.
 - **Trending shares the /skills shell**: `/skills/trending` uses the full-width layout from `/skills`. Its heading replaces `CompactPageHeader` and lines up with the results column. A sticky 14rem sidebar holds the range links, then the weekly CTA and the skilld install. Nothing sits right of the board, so the board takes every column the sidebar leaves. Rows switch on their own width, and the post carousel shows two cards where it has room. On narrow screens the ranges are a compact row above the board, and the CTA stays after the fifth row. Harlan asked for this on 2026-10-06. It supersedes the 2026-10-01 call that dropped the 9/3 sidebar for taking a quarter of the board's width: that sidebar sat right of a 64rem board, and this one sits left of a board that runs the full page width.
+- **Trending rows scan in one pass**: the rank is a plain mono number, and the first three are a step darker. Each metadata line runs source, stars, then the signal that ranked the row, and an empty slot renders nothing. Descriptions stop at two lines, the run chip is as wide as its command, and the post carousel shows whole cards only. The sidebar invitation drops the email preview and the card. Its button is the rail's one solid rose element, so the install chip beside it inks its dot. Harlan asked for this polish on 2026-10-06.
