Reduce dead whitespace and align the Reports charts to the cyber card language.
Layout only — charts, data and PDF export untouched.
- report_card_wrapper.dart: flat tonal fill + hairline outline + token radius
(was surfaceContainerLow + hard 16 radius, no border); uppercase telemetry
card title to match section headers.
- status_charts.dart / request_distribution_charts.dart: donut charts now use a
fixed 150px donut with an Expanded legend beside it (was an Expanded donut +
cramped right legend, leaving a large central gap); card height 220 -> 180.
Verified: flutter analyze lib clean; flutter build web green; visual QA (Reports)
in dark.
