Why 8 B matters

The claim (exact)

• Corpus: 10,000 little-endian int32 zeros → 40,000 raw bytes
• ZRW (pack v5): 8 bytes
• gzip-9: 73 bytes
• brotli-11: 13 bytes
• Ramp×1k: ZRW 8 B vs brotli ~1132 B (~141×)

Domain-honest: structured integers / zeros / ramps / walks. Industry GPs still win many general-byte cases. We route with OmniWave so one public product covers both lanes.

The site now breathes

As of this ship: hero leads with the flagship claim; a live proof bar polls metrics; standings hydrate on first paint (no empty “Loading…”); every response can carry X-Slid-Engine: alive.
