Retire the old EEC-based /gift reader-magnet pages

Neon Tan now ships via shop.michaelferrara.org/arc/neon-tan (bookshop's
ARC giveaway: single email field, gated download, tracked redemptions)
instead of these EEC-course-driven pages, which required first name as
well as email and served the epub from an ungated public bucket URL.

Old /gift and /gift-thanks paths still work via Caddy's path_redirects
(reground-infrastructure), so any existing bookmarks/emailed links keep
resolving to the new page instead of 404ing.

-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."
