+Add pencil icon hover affordance and save/error callbacks to InlineEditCell, plus loading spinners to three form submit buttons (Login, Register, Budget Create).
 
 Purpose: Make inline editing discoverable (pencil icon on hover) and prepare the callback interface for row-level flash feedback in downstream plans. Make form submissions feel responsive with spinner indicators.
 Output: Enhanced InlineEditCell with pencil + callbacks, spinner-enabled Login/Register/BudgetSetup forms.
+
+Note: CONTEXT.md specifies spinners on "all four forms: Login, Register, Budget Create, Budget Edit." No Budget Edit form component exists in the codebase — only BudgetSetup (create-only). Budget Edit spinner is deferred until that form is built. This plan covers the 3 existing forms.
