Widths the CDN edge whitelists (DoS guard — see apps/cdn-proxy WHITELIST_WIDTHS). Requesting any OTHER width returns HTTP 400 at the edge (unsigned URLs). These are the 1× base ladder values; DPR ×2/×3 multiples are applied + whitelisted server-side. Import this instead of hardcoding magic widths so an unsupported size is caught in review/IDE.
