RTL languages support.

An example for the Arabic language (https://learnxinyminutes.com/ar/html/):
- The paragraph text before the code block is displayed left-to-right (LTR) instead of right-to-left (RTL).
- Mixed-direction content (Arabic sentences containing English words/terms) becomes visually jumbled, with punctuation and word order appearing incorrect.

Code blocks render as expected; the problem is limited to the non-code paragraph section in the Arabic version.

### Expected behavior

- All Arabic paragraphs render in RTL with correct alignment and ordering.
- Inline English words remain LTR while the surrounding Arabic text remains RTL, without breaking punctuation or layout.

**Actual behavior**

- Arabic paragraphs render as LTR and mixed Arabic/English text appears messy and hard to read.

**Notes**

- This occurs specifically in the Arabic localized content (pre–code block text).
