Note

Medium Risk
Primarily visual and layout changes, but it also introduces a new hideIcon prop and changes inline action/close button sizing and styling, which could affect existing Alert appearances and spacing in consuming apps.

Overview
Updates Alert to a redesigned banner style where default and inline variants share the same base container styling and status-based border/background colors (including new light/dark theme aliases), removing the old top gradient bar.

Adds an opt-in hideIcon prop, adjusts icon/close button sizing, and for inline alerts applies ButtonContext overrides to style inline actions consistently (with new .inlineAction layout rules). Storybook stories are expanded to cover the new variants, hidden icon, and inline action examples.

Redundant neutral CSS block duplicates parent defaults

Low Severity

The &.neutral block sets border-color and background-color to the exact same --alert-color-border-neutral and --alert-color-bg-neutral values already declared on the parent .default, .inline selector. Every other status variant (error, info, success, warning) overrides the parent defaults with distinct values, but &.neutral is purely redundant since neutral is effectively the "unset" state.
