   The ten behaviour pages. Long form, so this is the .longform variant from
   README_TEN_BEHAVIOURS.md rather than the house scroll spec: body 1.12rem
   against the house 1.02rem, and a body colour a step darker than muted,
   because 1.02rem muted is right for a scroll you skim and too small and too
   light for two thousand words you actually read. Measure stays 64ch, line
   height stays 1.62. Matt's call, 4 September 2026, test and learn. */
