- 16 commercial scrapers: replace TIP-Bot/1.0 with Chrome/120 UA (GBICS confirmed returning 0 bytes for bot UA, Chrome UA returns 200KB) - gbics.ts: fix User-Agent (was returning empty HTML, now returns products) - optictransceiver.ts: disable — domain repurposed as plant shop (2026-04-06) Alocasia Regal Shield is not a transceiver.
