- Render HTML emails in sandboxed iframe (srcdoc) for true-to-life
display with complete CSS isolation from app styles

let them handle their own theming

support, with re-inversion for images/media to preserve appearance

text, showing only sender and subject for maximum information density
- Add visual density preview in appearance settings showing a 3-row
email list mockup that reflects each density option
- Fix global font size setting only changing line height by moving
font-size from body to :root so rem-based Tailwind classes scale
- Apply extra-compact behavior to email list items, thread list items,
thread email items, and thread conversation view (EmailCard)
- Update email list virtualizer size estimates for extra-compact
- Add extra-compact translations for all 8 locales
Rename "List Density" to "Density" and apply spacing changes globally
instead of only to email list item heights.
- Replace hardcoded padding/gap values with CSS custom properties
(--density-item-py, --density-item-gap, --density-header-py,
--density-card-p, --density-sidebar-py) set via JS on :root
- Apply density-responsive spacing to email list items, thread views,
email viewer, sidebar, navigation rail, contacts, and calendar
- Use inline styles instead of Tailwind arbitrary value classes to
avoid Turbopack compilation hangs
- Rename listDensity → density in store, types, and components
- Add persist migration (v1 → v2) and onRehydrateStorage callback
