Add a hero image (rendered from the redesigned PDF's own cover) so the
opt-in page shows the actual resource instead of pure text, and make
the post-submit message PDF-specific with a working /gift-thanks
fallback link instead of a generic dead-end "check your inbox" line.
Both are opt-in per-page params (hero_image, success_message) so the
real drip-course page's rendering is unchanged.
The Linode bucket added unnecessary indirection for a single small
static image. Commit will.jpg under static/images/ and point the
homepage at it directly; the now-orphaned copy has been deleted from
the reground-downloads bucket. The freebie PDF stays on
downloads.reground.org, unaffected.
