PostEx 0.3.0a2 — Expanded Built-in Palette Library

This prerelease expands and reorganizes the built-in library to 154 poster palettes:

• 50 Chinese university emblem cards following the 2026 ShanghaiRanking Chinese Universities Ranking;
• 50 foreign university emblem cards selected from the 2026–2027 U.S. News Best Global Universities ranking;
• 35 authorized Genshin character cards, with five characters from each of seven regions;
• 19 Chinese city cards rebuilt as complete, bright photographic frames without neural background removal.

The display order is now Chinese universities, foreign universities, Genshin characters, and Chinese cities. City palette extraction rejects near-black and near-white pixels and weights chromatic pixels to avoid the dark, muddy palettes in the first alpha.

The release also adds enlarged HUST and Tsinghua examples that place the full emblem beside six semantic color roles, hex values, and usage ratios.

postex palette-catalog --show-blockers audits all 154 entries. Third-party artwork remains subject to assets/palettes/rights.yaml and is not relicensed under Apache-2.0.
