An earlier "already applied" claim on this field was wrong -- it still held the diff's from value verbatim, not its to. Re-fetched 2026-09-13: the catalogue still shows live per-card prices with working Add to Cart controls -- Blackhole p100a $999, p150a $1,399, p150b $1,399; Wormhole n150s $999, n150d $1,099, n300s $1,399, n300d $1,449 -- unchanged from the 2026-09-06 figures already stored in pricing.note. Repoints from the Dev Day newsroom announcement to the vendor's own current catalogue, the source that actually carries today's prices.
