Harden

pbakaus/impeccable

Takes your interface code and systematically hardens it against real-world chaos. Adds proper text overflow handling with CSS clamps and ellipsis, implements i18n-ready layouts that won't break with German translations or RTL languages, and builds in error states for network failures and edge cases. Particularly good at catching the stuff that looks fine in demos but breaks in production, like what happens when someone enters a 500-character name or your API returns a 429. It's the difference between code that works with perfect test data and code that survives actual users.
