Subject: [PATCH] fix: prevent numeric input from resetting to zero on blur
 without edit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a numeric input field was focused but not edited, the blur handler
called toNumber(null) which returned 0 via parseFloat(null) → NaN → 0.
Now we skip emitting the update when numericTemp is null (no edits made).
