Lighthouse v1.4.33 a11y pass flagged "heading elements not in
sequentially descending order" (score 91/94). Three offenders:
- `<TherapyTimeline>` (insights/medikamente sub-page): sr-only
drug-name heading was an h4, but the parent SubPageShell ships
the only h1 and CardTitle is a <div>. Promoted to h2 so the
outline stays h1 -> h2 without skipping levels.
- `<FeedbackInboxDetailSheet>`: metadata + screenshot section
headings rendered as h4 inside a ResponsiveSheet whose dialog
title is h2 (Radix default). Demoted to h3 to stay sequential
beneath the sheet title.
- `<RemindersSection>`: results heading was h4 inside the admin
SectionFrame's h1. Promoted to h2.
Coach panel headings (IW5 surface) audited but not changed.
