.personal-report-reader declared --report-paper, --report-rule and
--report-accent on itself. A custom property resolves from the nearest
element that declares it, so an element-local declaration beats :root
regardless of media queries or source order — the dark override added
with the theme was dead the moment it was written.
The inks did follow the theme, because they live on :root. So dark mode
put --color-ink (#f2f0ea) on paper that stayed #f8f5ee: 1.05:1 for
headings and 1.22:1 for body. The report was effectively invisible.
Printing had the same defect from the other side: the print block forces
white backgrounds but never reset the inks, so printing from a dark
screen produced a blank page. It now pins the palette back to light —
paper is always paper.
Every report ink now clears AA on report paper in both themes, and the
new contract test forbids re-declaring the report palette anywhere but
:root, which is the trap that caused this.
