chore: switch decorative CJK from Japanese to Chinese, drop em-dashes

- Translate every Japanese kana/kanji glyph on the page to Simplified
  Chinese: side rail, CyberGrid lexicon rail, folios, footer, scramble pool,
  partner header (e.g. 流動性デスク -> 流动性交易台, katakana terms -> 哈希/流动性/深度/…).
- Remove em-dashes from the remaining code comments.
- Tighten two thesis lines that read as AI filler.
