Simplified Chinese installs the zh-Hans locale, a tiered two-pack font stack, and the
zh-hans-pinyin IME registration used by the built-in Pinyin input backend.

The bundle ships:
- zh-hans-core: the common-glyph UI/content font loaded first for fast startup and lower steady-state RAM use
- zh-hans-ext: the remaining Chinese glyph coverage that the runtime can load on demand as a content supplement
- zh-hans-pinyin: the built-in Pinyin IME registration layer

Use this bundle when you want a Chinese interface, Chinese text entry, or reliable
rendering of Chinese names and chat content while another locale remains active, without
paying the full monolithic CJK font cost up front.
