Form-free pages no longer carry form-validation weight

Pages that don't contain a form, like the public roadmap and its search bar, now load without dragging along code they never use.

Our text inputs quietly pulled in the entire form-validation engine wherever they appeared, even when there was no form to validate. Because the public board's search box uses the same input, every visitor was paying for validation logic that never ran.

We made that validation load only inside real forms, and did the same for the sign-in dialog wrappers that ship on every page in the header. The sign-in controls now appear a hair after the page does, an interaction nobody reads top to bottom, so the trade is invisible.

The payoff is a smaller initial download on the pages most people see first, which means quicker, smoother loads across the board.
