Restore original reader-magnet copy as the ARC page logline

The old /gift page's actual visible pitch ("The world is stranger than
it looks...") got replaced with the book's back-cover blurb when this
file was first created — this was the wrong text to lose; the blurb was
only ever used as /gift's SEO meta description, not its visible copy.

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."
