Top-level site navigation with mega-menus — a horizontal bar of

Triggers, each potentially exposing a rich Content panel.
|

One submenu open at a time; hover or focus on a sibling Trigger
|

while another is open swaps Content without a close/re-open
|
|
cycle. Soma owns active-item state + hover delays
|
|
(<code>openDelay</code> / <code>skipDelayDuration</code> /
|
|
<code>closeDelay</code>) + the indicator rect CSS vars +
|
|
directional swap motion (<code>data-motion</code>).

Root renders <code><nav></code> with translated <code>aria-label</code>
|
|
("Main"). Each Trigger has <code>aria-haspopup="menu"</code>,
|
|
<code>aria-expanded</code> and <code>aria-controls</code>; Content
|
|
is the labelled mega-menu region. Links use <code>aria-current="page"</code>
|
|
when the route matches.
