/* Redis sorted sets — Salvatore Sanfilippo's "give people powerful primitives and do
   less," made visible. A live ranked leaderboard is painful in a traditional database
   (re-sort and re-rank on every score change) but trivial in Redis: it is one sorted
   set. Each player is a member with a score; the set stays ranked automatically. Bump
   a score and the board re-orders on its own -- the equivalent commands are just ZADD
   to set a score and ZREVRANK to read a rank. A complex feature collapses to a few
   commands because the right primitive already exists. Vanilla JS, no deps, no build.
   Palette shared with siblings: green = the just-updated member (the win), neutral
   otherwise. No red. */
