Swahili translation review (part 04)

Scope: 23 files in developers/docs/ — spot-checked 10 files, grep-scanned all 23.

Issues found and fixed

''text'' Crowdin artifacts (fixed in 9163e9e):

• developers/docs/index.md — title, description, and 3 body paragraphs wrapped in ''..''; title also had spurious trailing period
• developers/docs/intro-to-ether/index.md — title wrapped in ''..''; one mid-paragraph sentence wrapped in ''..''

Scanned clean (no issues)

Pattern	Result
Translated frontmatter tags	None found — no tags: field in these files
"Solidity" → "Uimara"	Not in changed files (1 hit in community/support/ outside this PR)
Translated code/console.log	No code blocks with translated strings
Translated GitHub handles (kwa-username)	None
Escaped asterisks \*\*	Present in evm/opcodes/index.md — matches English source (mathematical notation 2**256), not a bug
Broken bold markdown	None
Translated brand names / units	ETH, Wei, Gwei, Gas, EVM, DeFi, NFT, MEV, Beacon all preserved correctly
URL integrity	All links intact

Translation quality notes

The Swahili translations in this batch are generally good. Technical terms (EVM, gas, MEV, DeFi, staking, etc.) are preserved in English where appropriate. Some Swahili technical vocabulary choices are consistent (e.g., "mnyororo wa bloku" for blockchain, "mikataba-erevu" for smart contracts, "wathibitishaji" for validators). The content reads naturally and the file structure/MDX components are all intact.
