Replaces the portal-y dashboard shell (hero context strip, sidebar nav,
summary strips, fact chips, kicker labels) with a flat, disciplined layout:
- Identity bar: compact inline h2 + role + account kind
- Tab bar: simple horizontal tabs with active underline
- Content panels: direct workspace table / access roster / billing cards
without redundant per-section page headers or summary stat strips
- Simplified block headers: account name + actions only, no fact chips
- Support section: direct h2 + help text, no page header wrapper
CSS rewritten from 5492 lines to a minimal flat design system:
white background, no shadows, no gradients, 6px radius, system fonts.
All 79 tests updated and passing.
