+Move `lucide-react` from `^1.31.0` to `^1.43.0` in every package that declares it, and
+repair what the jump breaks, so icons resolved from a STRING keep drawing a glyph.
+
+Measured once against the installed 1.43.0 artifact when this change was made; nothing in
+the repository re-derives these readings. Across the jump lucide removes no runtime export,
+no public type name and no `lucide-react/dynamic.mjs` name, and every name this repository
+imports from `lucide-react` resolves. Exactly one key leaves the runtime `icons` record:
+`Trash2`, retired in favour of `trash`.
+
+What a user sees change:
+
+- Icons the lazy icon seam draws (`resolveIcon`, objectui#9251) get their path data again.
+  lucide 1.43.0 icon modules export their path data inside `__iconData` and no longer
+  export `__iconNode`; the seam now reads both. Reading only `__iconNode` against 1.43.0
+  leaves every such glyph an empty box, with nothing thrown or logged.
+- `DetailView`'s delete action and three schema-catalog examples spell their icon
+  `trash`, not `trash-2`, so they keep resolving. The glyph is unchanged: 1.43.0's `trash`
+  path data is byte-identical to the `trash-2` path data of 1.31.0 and 1.35.0. Anything
+  that already authored `trash` now draws that same artwork, because lucide moved it under
+  the `trash` name; a few other glyphs were also redrawn upstream.
+- Icons imported as COMPONENTS carry lucide 1.43.0's own classes: one class per declared
+  alias (a spinner renders `class="lucide lucide-loader-circle lucide-loader-2 ..."`), and
+  no longer the class lucide used to derive from the PascalCase key where that differs
+  (`ArrowDown01` no longer carries `lucide-arrow-down01`). The canonical
+  `lucide-<icon name>` class is still there, so a `.lucide-loader-circle` selector still
+  matches.
+- Icons resolved from a STRING through the seam keep the classes they had: `lucide`, the
+  canonical `lucide-<icon name>` class and the key-derived class. They do not carry
+  lucide's per-alias classes. That is a maintainer ruling (objectui#8941, option C): the
+  alias list lives only inside each lazily loaded icon module, and it was not moved into
+  the eager name list. A selector that targets an alias class matches a component-imported
+  icon and not a string-resolved one. This also dates the example in the objectui#9251
+  entry: `trash-2` no longer resolves as a string, so no seam-drawn glyph carries
+  `lucide-trash2 lucide-trash-2`; a digit-bearing name that still resolves, such as
+  `arrow-down-0-1`, carries `lucide-arrow-down01 lucide-arrow-down-0-1`.
