PR Summary

Medium Risk
Introduces a new NumberInput plus non-trivial BaseInput styling/behavior changes (fit-content sizing, clear/edit icon layout, number spin-button handling) that can affect all inputs using BaseInput across variants and browsers.

Overview
Adds a new NumberInput component (integer/float) built on BaseInput, including parsing to number | null, integer key filtering, and wheel-scroll prevention while focused.

Updates BaseInput/baseInputRecipe to better support number inputs and icon/clear/edit layout: removes the fit-content sizer span in favor of CSS sizing, adds rules to hide/neutralize browser number spin controls, and refines clear/edit visibility/spacing (including a hideClear slot and new variant flags).

Exports NumberInput, adds comprehensive NumberInput Ladle stories, and includes a changeset bump; minor story styling tweak to TextInput.

🤖 Augment PR Summary

Summary: Adds a new NumberInput component to the design system, built on top of the existing BaseInput.

Changes:

• Introduces NumberInput that adapts numeric value/onChange to BaseInput’s string-based API
• Adds a comprehensive Ladle story file showcasing variants, states (disabled/invalid/loading/placeholder), alignment, styled values, sizing, widths, and prefix/suffix configurations
• Extends baseInputRecipe with additional slots/variants to support “hidden clear” behavior and number-input browser controls
• Updates BaseInput to compute and pass hasBrowserControls and willClear styling flags and to hide the clear affordance without layout shift

Technical Notes: Includes CSS to suppress native number spin controls in some states and disables scroll-wheel value changes while the number input is focused.
