[tzz-radxa]

Summary

• Use 瑞莎 for the brand in Chinese ROCK 5B guide prose while retaining Radxa in English prose and technical identifiers.
• Align Chinese punctuation and spacing in four guide pages; fix matching English punctuation, spacing, and a possessive typo.

Why

The ROCK 5B introduction, power, eMMC, and enclosure guides contain mixed-language branding and inconsistent prose punctuation. The Chinese accessory index already calls the eMMC module 瑞莎 eMMC 模块. URLs, component properties, product model identifiers, numeric values, headings, and anchors are unchanged.

Verification

• pre-commit run --files <all eight changed pages> passed.
• ./scripts/agent-doc-lint.sh <all eight changed pages> passed.
• python3 scripts/generate-agent-product-index.py --check, ./scripts/agent-doc-drift-guard.sh, ./scripts/agent-doc-translation-guard.sh, and git diff --check passed.
• python3 scripts/github_pr_guard.py check --repo-path <task worktree> reported one scope, eight paired files, no reasons. A fresh fetch in the guard failed due to local DNS resolution; the upstream base was fetched immediately before the worktree was created.
• Full Docusaurus build not run: this content-only checkout has no site application or package.json; the application lives in the separate docs-template repository.
