Real-content fixture for the end-to-end pipeline. TH-141 (39 parts: 22 segment, 15 lemma, 2 example) migrated from the prototype's typst `#let parts` manifest to ADR-0008: declarative manifest.toml (project+info+ordered parts+targets) + per-element element.toml (kind + scalars; examples carry `source`). Content .typ files copied byte-identical (no math corruption); per-element main.typ + meta.toml dropped (wiring is now generated). Part order matches source exactly; 5 lemmas have no proof.typ (optional); no cross-file imports / paralearn refs / figs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

该量级谱可由缺键模型 @固气缺键式 解释。分子晶体的键合主要是范德瓦尔斯力，$L_s$ 小、$gamma$ 小；离子晶体的键合包含库仑作用，$L_s$ 上升一个量级，$gamma$ 也随之上升；金属内部的金属键键合最强，$L_s$ 最大、$gamma$ 最大。同一公式横跨四个数量级的物理体系都给出对的量级。
