The app HAS a platform layer -- AnchoredPopover (22 importers, with arrows/typeahead/Escape/anchor-flip), QueryState (21), Modal (17), PageShell, DataTable, Tabs, Tooltip and ~26 more -- but it sat flat among ~160 feature components with nothing marking it as one. Several of those files describe themselves as 'the one place' or 'canonical' and were still bypassed by hand-rolled markup, because a layer nobody can see is a layer nobody uses; three separate inventory passes of this codebase misread it the same way. Moves the 33 domain-free modules into components/ui/, rewrites the imports in 89 files, and makes the boundary a lint rule rather than a convention: inside ui/ a one-level-up import (a feature component) and any lib/api slice are errors. The rule was verified to fire on both and to leave generic lib/ helpers alone. README.md states which side of the line a component belongs on and why. No behaviour change: 3x tsc, eslint, knip, prettier and 687 vitest tests all green; no backend file touched.
