Platinum phases 4 and 5: containers face one way, and nothing grows Two container primitives, and the rule that picks between them: does the user look at the thing, or into it? `raised_frame` is a card laid on a panel (surface_raised fill, Raised bevel); `inset_well` is a hole in one (surface_page fill, Inset bevel, one point of inner margin so content does not sit under the frame). info_banner and warning_banner become raised cards. Both were filled `surface_sunken` -- the well colour -- while being shaped like neither a well nor a card, so the fill moved rather than the bevel being pasted over a contradiction. The sync panel's error box is the same shape and now says so through the same helper instead of hand-rolling a Frame. The file-list table body and the sidebar's tag tree become wells. The table needed its column-visibility snapshot hoisted above the well, since a `&state.column_config` borrow cannot survive into a closure that also takes `state` mutably; the local bools it already kept for the same reason inside the table closures now serve both. `clicked_col` stays outside so the sort toggle still runs after every table borrow has ended. Phase 5: `hovered.expansion` to 0. A widget that swells a point under the cursor fights the light model directly -- the bevel is painted on the response rect, so an expanding widget drags its own frame outward while the surface under it stays put. Feedback comes from the bevel inverting on press, which is a stronger signal and costs no layout. settings_panel.rs and footer.rs are named in the phase-4 spec but had nothing left: their paint sites are the theme swatch and the progress bar, both converted in the pills pass. instrument_panel.rs and edit_panel.rs stay untouched, as the spec requires. 345 tests green, clippy at its prior warning count.
