about

nx_css_boxmodel_gate.nx -- PROOF (re-runnable) of the S21 height-axis rung: `padding`/`margin` SHORTHANDS and the `font` shorthand's font-size now shape layout. Real pages set the box model almost entirely through shorthands, which the longhand-only lookups ignored -> we rendered ~40% denser than Chrome. Every test runs the REAL br_layout on an inline fixture and asserts EXACT geometry: T1 padding:8px 12px -> the padded block grows 16px taller AND its text indents 12px T2 margin:10px 0 30px -> vertical rhythm between two paragraphs == 17+10+30 = 57px T3 margin:2em 0 (fs 20) -> em resolves against the INHERITED font-size (40px) T4 font:15px/1.55 ... -> BOTH resolvers (layout inherited + paint br_comp_fontsize_inh) read 15 T5 longhand priority -> padding:8px 12px + padding-top:1px -> top is 1 (longhand wins) T6 CAN-FAIL control -> the same fixtures WITHOUT shorthands do NOT move (the deltas are real) license_tier: ORIGINAL expect_exit: 0
