/* ---------------------------------------------------------------------------
   query/query.css — the Query module's own stylesheet.

   The Query module IS the database module — `shell-db-frame` + `CustomerGrid` —
   so the frame, the grid and every view kind are styled by rules that already
   exist. What is left here is what this surface adds: the VIEW RAIL (owner item
   3: the AI's views, grouped by the database they read), a one-line provenance
   disclosure, and the empty state.
   ⚠ THE UNIVERSAL DATABASE HEADER IS GONE FROM THIS FRAME (owner item 7,
   W36-T67), so the rail's group heading is now the only place the source
   database is named. That is not a gap: it was always the richer of the two,
   carrying the icon as well, and the header was the copy.

   The chat rules live in `assistant/assistant.css` with the markup they style.

   EVERY FONT SIZE IS A `--lp-fs-*` TOKEN AND EVERY COLOUR A `--lp-*` TOKEN.
   Wave-21 R5 is gated app-wide over every CSS file under src, and a literal
   here reds `web_ui` for the whole tree. No emojis, no ALL-CAPS chrome
   (DESIGN.md R6).

   AND DO NOT WRITE A GLOB IN THIS COMMENT. A star-star followed by a slash
   spells the CSS COMMENT TERMINATOR — the comment would end in the middle of
   its own explanation and `lightningcss` would die far from the cause. Found
   by `web_build` in wave 32's QA; it blocked the deploy outright.

 *
 * ⛔ GEOMETRY ONLY. `StarButton` is B's component and `starred.css` owns everything about how it
 * looks; overriding its colour or its glyph here would be a second opinion about one mark. What a
 * rail row genuinely needs different is placement: the shared rule is `position: absolute` on a
 * TILE wrapper, and this row is a flex list whose right end already holds the actions button, so
 * an absolutely positioned star would sit on top of it.
 *
 * ⚠ AND THE REVEAL RULE HAS TO BE RESTATED, not inherited. The shared sheet reveals the star with
 * `.st-tilewrap:hover`, a wrapper that does not exist here — so without the row's own hover rule
 * the button would be `opacity: 0` forever except when starred or focused, i.e. a control you can
 * only find by tabbing to it. `.is-on` and `:focus-visible` keep working from the shared sheet.
