/* Inset "well" — the Artix wiki's code blocks (darkstrap `pre`): a panel that
   reads as pressed INTO the page — the page colour darkened, a dark inner
   shadow under the top edge, a faint light catch-line under the bottom edge.
   Shared by the chat's thinking/tool blocks (LazyCollapse) and the sidebar
   views (TilePanels). darkstrap: background rgba(0,0,0,.3); box-shadow
   rgba(255,255,255,.1) 0 1px 0, rgba(0,0,0,.8) 0 1px 7px 0 inset; radius 4px.
   Ported onto the active daisyUI theme so it always matches, and toned down a
   step: the fill is the theme's page colour (base-100 — both the chat and the
   sidebar sit on it) darkened 18% (darkstrap: 30%), computed OPAQUE and exposed
   as --inset-well-bg so sticky children can paint the same colour; the inner
   shadow is 0.6 (darkstrap: 0.8); the catch-line is the theme's text colour at
   10% instead of plain white. In @layer components so utilities can override. */

   Shared by the workspace top bar (App) and the home page header. Ported onto
   the active daisyUI theme so it always matches. darkstrap's bar is LIGHTER
   than its near-black page (that's what makes the shadow read), so the
   gradient is shifted to keep that relationship on our lighter page: it runs
   from the page colour (base-100) lifted 20% toward the text colour down to
   base-100 lifted 3%. No bottom border (darkstrap has a 1px #030303 one —
   removed by user request; the gradient + shadow carry the edge). The shadow
   is 0.5 (darkstrap: 0.1 — invisible on our lighter page). Positioned +

/* Raised — the INVERSE of `.inset-well`, for things that pop OUT of the page
   (the home page's workspace tiles). Where the well has a dark shadow INSIDE
   under its top edge and a light catch-line OUTSIDE below it, a raised surface
   has a light highlight INSIDE along its top edge, a soft shadow OUTSIDE below
   it, and a faint top-lit gradient over its own colour (lighter top → darker
   bottom — convex, where the well is concave). Built on Tailwind's shadow
   variables (not a bare box-shadow) so it COMPOSES with the ring / shadow
   utilities: the inner highlight rides --tw-inset-shadow (kept by
   `hover:shadow-xl`, rings, drag), the drop rides --tw-shadow (which
   `hover:shadow-xl` / `shadow-2xl` swap for a bigger lift). Works on any
   background colour (the tiles' tone colours), so it always matches the theme. */
