Own page, not a modal — a visitor arriving with no account yet from a PopEd deep link shouldn't be dropped into an app-shell overlay. Lighter chrome (no Library / My Bookshelf / Account nav) until they're actually in.

Banner leads with the specific lesson the visitor clicked from (deep-linked from a grade/topic search on populationeducation.org), since that's the "wait, what am I buying" question a deep-linked visitor has.

Badges show the concrete value for each tier instead of generic labels. This unit now pairs the Unit name with its grade band (Habitat & Species · 6–8) since a Unit always sits within one band — makes that scope visible right on the tile, not just in the description text below it. Full library pairs "Everything" with all 4 grade bands spelled out, for the same reason in reverse (it spans every band, so say so). This grade band keeps its single band badge (6–8, matching where this visitor came from). "This topic" is now "This unit" throughout — a Unit is what's actually purchased.

Back to showing a highlight of individual resources (not Unit-level summary cards) — same tile style as Library/Collection/Login previews (image, type badge, grade/subject, one-line teaser, "Learn more"), so this reads as consistent with every other preview grid in the wireframes rather than a one-off component. Capped at 6 per tier, then an "And Much More" link out to populationeducation.org for the full catalog rather than an exhaustive in-app list.
