+  * All four GUIs: correct the encoding help text. It claimed the input must not
+    start with `0x`, `0b`, or `N'h`, but a hex float such as `0x2.4p3` does start
+    with `0x` and is encoded, exactly as the line above it in the same help says.
+    Only a plain bit-pattern in one of those notations switches to decoding.

   - Enter a decimal value (2.5, -4.1e5) or hex float (0x2.4p3).
   - You can pass NaN, Inf, -0, -Inf for special values.
   - For floats, pick a rounding mode.
-  - Input must NOT start with 0x, 0b, or N'h (else we decode instead).
+  - Plain 0x, 0b, N'h patterns decode; hex floats (0x2.4p3) encode.
 
 Decoding:
   - Use hex (0x), binary (0b), or Verilog (N'h) notation.
