/* ===== overview_tab_html (HTML form, scoped) =====
   The form's rules (Anvil strips <style> from an HTML template). Loaded eagerly
   from anvil.yaml native_deps.head_html, which is also what styles the
   designer canvas.

   `.ov-root` is the wrapper around `#ov-shell` and
   `#ov-modal-backdrop`: two meaningful top-level nodes would leave Anvil's own
   wrapper as the form root. It is the form root, so its rule stays a bare
   class — the one selector that must outrank the scoped rules beneath it.
   Everything else is `:where(.ov-root)`-scoped, which adds zero specificity and
   so cannot change which rule wins.

   The root takes `position: relative` (guide: an HTML form root takes it).
   The wrapper carries NO display declaration: test_detail_html
   shows and hides this form with `visible`, and a `display: contents` root
   would be in a specificity race with whatever rule Anvil's visible=False
   uses. A plain block adds no box of its own — `.ov-shell` neither grows nor
   sets a height inside the mount panel's flex column. The root takes no
   min-height, height or overflow.

   No `.ov-*` class is declared anywhere else in the app and the form applies no
   `.px-*` class in static markup, so this sheet has no tie to audit against a
   sibling form or against the dependency's runtime theme injection. Every
   selector below is class-led, so none of them can lose to a bare element
   rule in theme.css on document order. */
