Non-modal menus:
- DropdownMenu + ContextMenu default to trapFocus=false + preventScroll=false
(were modal — hard focus-trap + body scroll-lock that made them feel stuck).
Menus stay navigable while open (Chakra-style); the props remain for an opt-in
modal menu. morfo focus.trap=false + the demo control defaults aligned.
list-surface — ONE shared size source for list surfaces:
- new lib/list-surface.css (--list-* keyed on [data-list-surface][data-size], 1:1
with the control sizes) + lib/list-surface-context.ts (shared size context for
portaled sub-panels). DropdownMenu/ContextMenu/Menubar/Listbox bridge their
--{c}-* size tokens to --list-*; ContextMenu gained the size axis it lacked.
Row-height doctrine — unified to CONTROL-HEIGHT:
- archetypes.css [data-archetype=item/option] gains a fallback-guarded control-
height FLOOR (min-block-size: var(--list-item-height, auto) + padding-block:
var(--list-item-py, var(--space-1-5))) — ZERO regression off a list-surface
(the ~45 non-list archetype consumers are untouched). Select/Combobox/Command
stamp data-list-surface so their option rows inherit the floor, matching menu
items. Verified: select option md 36px / lg 44px = menu items; bare archetype
item unchanged (0 floor, --space-1-5 padding).

The event-trace inspector in each demo keyed its `{#each}` by a
`Date.now()` timestamp (`entry.at` / `h.at`). A single interaction can
stamp `data-event` on several elements within the same millisecond, so
two trace entries share the key and Svelte throws `each_key_duplicate`
(reported on dropdown-menu).
The trace is an ephemeral, 3-item, text-only log with no transitions or
stateful children, so positional reconciliation is correct: drop the
timestamp key (the each becomes unkeyed). The `fmtTime(...at)` display is
left intact.
Swept all 22 demos carrying the pattern (21 keyed by `entry.at` + announce
by `h.at`): dropdown-menu, context-menu, menubar, navigation-menu, listbox,
grid-list, table, tree-view, tree-grid, feed, command, carousel, drag-drop,
clipboard, announce, alert-dialog, button, color-field, link-preview,
range-calendar, time-field, time-range-field.
Verified: `as \w+ (\w+.at)` -> 0 occurrences site-wide; `npm run check`
0 errors; browser repro on dropdown-menu + table (burst of events, no
each_key_duplicate, console clean).
