Walkthrough

Documentation sentence in the gas rebates conceptual guide was replaced: the previous claim about processing ~10% of daily Ethereum transactions was removed and replaced with a statement that MEV Blocker operates the only permissionless Order Flow Auction binding searchers and builders to public rules.

• Single-file documentation text replacement; no code, tests, or behavioral changes.
• Review focus: ensure phrasing accuracy and no unintended edits.

Poem

🐰 A line trimmed gentle, snug and bright,
Replaced with rules that stand in light,
Builders, searchers bound to play,
In public halls they find their way,
A rabbit hops — the docs delight! 🥕✨

Learning: When referring to MEV Blocker or other products/services in documentation, use "that" instead of "who" as the relative pronoun (e.g., "MEV Blocker is the only RPC that has..." not "MEV Blocker is the only RPC who has...") because products are not people.

Applied to files:

One small lower case issue to address.
