/*
 * The "ihasmail" theme: the palette from ihasmail.org, which is a teal-navy
 * rather than the blue-slate of the plain dark theme, warmed by the orange the
 * logo's cat is drawn in.
 *
 * It rides on data-theme="dark" rather than replacing it, so every dark-only
 * rule further down this file -- tooltips, toasts, the message frame -- keeps
 * applying without being duplicated. Only the palette is overridden.
 *
 * Specificity is doing deliberate work here. This block is [data-palette] plus
 * :root, so 0,2,0; the accent variants below are :root[data-theme][data-accent],
 * so 0,3,0 and they win. That is what makes the accent swatches keep working on
 * top of this theme -- and because the default accent ("teal") has no rule of
 * its own, ihasmail.org's own accent is what shows until someone picks another.

/*
 * Layout containment here is a security control, not a layout tweak.
 *
 * Message bodies render in a shadow root, which scopes selectors but not
 * layout: a `position:fixed` rule in mail CSS is still positioned against the
 * viewport, so a sender could paint over the whole application. Containment
 * inside the shadow root cannot stop it — mail CSS lives in the same tree and
 * simply overrides it, and `:host` reaches the host element too (an
 * `!important` there even beats an `!important` from this file, because
 * importance reverses tree order). An ancestor of the host is the one thing
 * mail CSS has no selector for. `layout` rather than `paint`: it makes this a
 * containing block for fixed descendants without clipping tall messages.
