Use case: text-localization. Edit target: the provided rocket C3 design board. Change ONLY the large top heading 'RETURN-1 / C3' to the exact text 'rocketstar / C3'. The word rocketstar must be all lowercase, spelled r-o-c-k-e-t-s-t-a-r, with comparable polished silver typography in the same heading area. Preserve every other element as closely as possible: both entire rockets, their proportions, silver finish, black rounded vertical panel with exactly three cyan dots, cyan rings, landing legs, detailed inset, gray background, framing, AVOKADO text, LEEWARD, WINDWARD, SURFACE DETAIL, EXTERNAL DESIGN STUDY and material swatches. No redesign, no added logo, no added elements. Preserve the landscape aspect ratio. This is a naming update only.
