Translate Strings.dat to Simplified Chinese (479/496)

- cn_strings.py: full GB2312 translation table; make_cn_strings.py is now
  escape-aware so values containing escaped-quote formats survive.
- dump_all_strings.py + check_translations.py: dump the English table and
  verify the printf specifier sequence matches the source (0 mismatches).
- Skipped: pure-format/empty strings, the tutorial texture path, ambiguous
  key labels.
- DEVLOG notes the remaining engine-layout caveats.

+## 2026-09-20 — Full `Strings.dat` translation
+
+- Translated the `English` column for **479 / 496** entries (the rest are pure-format
+  strings, empty/whitespace values, the tutorial texture *path*, and a few odd key labels).
+- `tools/check_translations.py` verifies the printf specifier sequence (`%s`/`%d`/`%i`/`%%`)
+  matches the English source exactly (0 mismatches) and that every value GB2312-encodes.
+- `tools/dump_all_strings.py` dumps the source table to `build/strings_en.json`.
+
+### Known layout caveats (engine UI is tuned for the small Latin pixel font)
+
+- Some engine UI positions tab/button labels against a box sized for English, so short
+  Chinese labels can look left/right-aligned; a couple of centred dialogs jitter while a
+  teletype reveal is running.
+- In-game HUD button labels wrap and can overlap the shortcut hint because the boxes are
+  small; to revisit via a smaller CJK cell/advance if needed.
+
 ## 2026-09-20 — Chinese in the main menu (first playable)
 
 - Built `tools/build_cjk.py`: renders the full GB2312 set (7445 double-byte codes) as **12x12**
