Finish the Neon Tan reader-magnet page

Fill in the gift page's copy (title, description, subhead), wire the
cover image into the hero and og:image/Twitter card meta, and point the
download links at the real bucket path. Also fixes a bug where every
page's meta description fell back to the site-wide bio instead of its
own.

+description: "An AI's trademark silver-blue suit isn't exactly beach-town vibes, but he's determined to land his song a spot on the weekly top 40 countdown anyway. After a string of failed attempts to get noticed by the countdown's enigmatic curator DJ, he and his wisecracking seagull sidekick stumble into an open mic night just as a malware glitch hits, forcing him to trade analysis for improvisation, rallying tourists into one spontaneous singalong to discover connection was never something you could calculate."
