# Sample v2 — fixed 2026-07-30 BEFORE any measurement.
# Selection: category coverage, not traffic rank. Six strata, chosen because
# llms.txt targets documentation-heavy technical sites, so the interesting
# comparison is docs-heavy vs not.
# S1 dev tools & infra | S2 AI/ML | S3 API-first | S4 B2B SaaS (v1 sample)
# S5 docs/dev platforms | S6 ecommerce & website builders
