All four carry the same content: the one-liner, a three-paragraph explainer of what the system actually is, the 6 / 17 / 50+ scale numbers, the panel's three faces, and the featured rides. Anniversary and Fall use real ride names from map-config.yml; the other four events are placeholders at the counts you gave me.
The question you asked — lands, iconic rides, or a mix? — is really a question about what the organizing spine is. Each of these picks a different one. P5–P7 add the filter system you described. P8 and P9 are the ones to look at — they fix the three things you flagged on P5: the scrollbar under the filmstrip, the 17-colour lands grid, and the obnoxious ride catalog.
