📝 Walkthrough

Walkthrough

This update modifies the fault proofs explainer documentation by adding a new FAQ entry about guides for running the proposer and challenger roles. It clarifies that while these roles are open to everyone, typical users are not expected to run op-proposer regularly and may only need to propose a single output root if necessary, usually via the DisputeGameFactory contract through Etherscan. The prior instruction to use the create-game subcommand of op-challenger for proposing outputs is removed and replaced with a warning that this command is for testing only. The update also introduces explicit links to detailed op-challenger documentation.

90-97: Remove bold emphasis & streamline phrasing to match docs style-guide

Docs guidance discourages bold for emphasis and prefers concise, impersonal wording.

-It's not expected that normal users run `op-proposer` to regularly propose output roots.
-Users would generally just propose a single output root if they need to withdraw and the chain operator isn't proposing outputs for them via direct calls to the `DisputeGameFactory` via Etherscan.
+Typical users are not expected to run `op-proposer` on a regular basis.
+If a chain operator has not proposed an output, a user can submit a single output root by calling `DisputeGameFactory` directly through Etherscan.

-The [`create-game`](https://github.com/ethereum-optimism/optimism/tree/develop/op-challenger#create-game) subcommand of `op-challenger` is **for testing purposes only** and should not be used in production environments. It is not intended as a replacement for proper `op-proposer` infrastructure.
