- prefs API accepts the new rubric_debug key (off|on), the only new runtime
write in v1.1; every section_state body now carries prefs.rubric_debug.
- fillRank renders the tank gauge + rounded % by default; the breakdown
lines, audit footer and the quiet listing-enrichment fetch run only when
the pref is on. List rows and the card face stay rubric-free (unchanged).
- Trends 'Actions' gains a 'Why breakdown: off | on' row in the setMode
style; updateSectionUI repaints it on every section hydrate.
