From the editor

Verified that the previous fix landed correctly: [^2] has been removed from the "visible from space" citation, which now cites only [^4]. All remaining claims check out against their cited snippets: the bloom's location off New Jersey and Delaware is supported by [^4] and [^7]; the Mid-Atlantic Bight span from Massachusetts to North Carolina is supported by [^5]; and the growth since mid-April is supported by [^3]. No new issues introduced.
