Bundled media carry Next's per-deploy ?dpl= and were downloaded again after
every release. Bytes unchanged; /fonts/serif-sc/* is immutable. Overturns the
serif-headings contract line "bundled by Next, not served from public/"
per TASK-home-first-load-20260930 decision 2.

Renamed, sliced subset of Noto Serif SC SemiBold (OFL 1.1, noto-cjk
Serif2.003) covering the 6500 level-1 + level-2 characters of the
通用规范汉字表 plus Latin, punctuation and common symbols.
- scripts/fonts/build_serif_slices.py: fontTools subsetting into 30 woff2
slices + serif-sc.css (@font-face, weight 500 700, font-display swap);
byte-identical output for the same input.
- Frequency order (char_order.txt): repo corpus top 300, then Google
Fonts SC frequency bands (nam-files, Apache-2.0), then corpus count;
unranked characters sliced by contiguous code point.
- tests/test_serif_font_slices.py: coverage, no overlap, files exist,
120 KB cap; added to the quick quality gate.
