/* ===== edit_tab_html (HTML form, scoped) =====
   Loaded eagerly from anvil.yaml native_deps.head_html. Anvil's server strips a
   <style> block out of an HTML template, so the form's rules live here.

   ROOT RULE. `.et-shell` stays a bare class so it outranks the scoped reset. It
   takes `position: relative` and nothing else: this form is a section inside a
   classic panel, not a screen root in the layout's scroller, and it declares no
   `min-height`, `height` or `overflow`.

   SCOPING. Every other rule is `:where(.et-shell)`-prefixed, which adds zero
   specificity, so no rule can change which declaration wins on that account.
   Three rules stay BARE because the root itself is their ancestor with a second
   class - `.et-shell.archived .et-required-row` and the two
   `.et-shell.archived .et-actions ...` rules. Wrapped as
   `:where(.et-shell) .et-shell.archived ...` they would never match, since the
   root cannot be a descendant of itself.

   THE SELECT TIE, and it is why `.et-field` is TRIPLED below.
   `training_authoring`'s `.ta-root select`
   is the one selector in this section whose subject carries no form prefix, so
   it reaches this form's cooldown unit (`<select id="et-f-cooldown-unit">`).
   `.ta-root select` and `.et-field select` are both (0,1,1) and collide on
   padding, border-radius, background, color and font-size. `.et-field select`
   must win - the field renders with no chevron, `padding: 8px 12px` and
   `color: #0f172a`. As a head link this sheet is EARLIER than
   `training_authoring.css` (alphabetical order), which also writes
   `.ta-root.ta-root select` at (0,2,1). A doubled class here would tie that
   and lose on order, so the three colliding rules are written with a TRIPLED
   class at (0,3,1) and win on weight in either order.

   The triple carries to this sheet's own `:focus` and `[disabled]` rules, or
   the bump would silently reorder ties INSIDE this file:
     - `.et-field input:focus` (0,2,1) would lose to a tripled base (0,3,1) and
       the focus border/outline would stop applying;
     - `.et-field input[disabled]` (0,2,1) likewise, and the disabled fill would
       revert to white.
   Each is lifted to the same weight and sits after its base rule, so both
   pairs resolve as intended. `.et-cooldown-row select` is
   tripled for the same reason as the base rule.
   The `.et-invalid` type selectors are NOT tripled - they carry no `.et-field`
   ancestor and would reach `question_editor_html`'s fields. They keep their own
   weight and a separate `.et-field`-anchored rule restores the tie; see the
   comment on that rule below.
   `.et-field textarea { resize; min-height }`, `.et-cooldown-row input` and
   `[data-violation-field].et-invalid` declare nothing the tripled rules
   declare, so they are left alone.

   THE BANNER HOST. There is no `.et-banner-host:empty` rule: `__init__` puts
   `banner_panel` into the `et-banner` slot and `_dismiss_banner` clears the
   PANEL, not the host, so the host always holds an element child and never
   matches `:empty`. It is a zero-height flex item of `.et-shell { gap: 20px }`
   that consumes one gap whether a banner is showing or not. It keeps
   `display: block` and its box, so that gap survives; `display: contents`
   here would delete it.

   THE ARCHIVED BANNER. Inline attribute styles are banned in an HTML template,
   so the base rule hides it and `.is-archived` reveals it; the module toggles
   the class. No designer gate is needed: the canvas shows it hidden, which is
   its initial state.

   OTHER TIES AUDITED, none live. This form applies no `.px-*` class, so the
   dependency's runtime theme injection reaches nothing here. Anvil's own
   `theme.css` styles form controls only through `.anvil-component` /
   `.anvil-role-*` selectors, and every control in this template is raw markup
   inside an HtmlComponent, so it carries neither. `et-` appears in no other
   template or asset. No @keyframes in this form. */

/* `.et-field`'s base rule is tripled, so the (0,1,1) type selectors
   above do not tie it. The tie is restored HERE rather than by tripling
   them, because a tripled type selector carries no `.et-field` ancestor and so
   reaches `question_editor_html`'s own fields, which sit inside `.et-shell` and
   are the main consumers of `.et-invalid`: at (0,3,1) it would beat
   `:where(.qe-root) .qe-ans-text:focus` (0,2,0) and leave a flagged answer box
   pink while focused instead of white. Doubled - not tripled - so this rule
   sits exactly two classes above the (0,1,1) type selectors, mirroring the
   base rule's own +2, so the cascade inside `.et-field` holds in full: it
   ties the tripled base (0,3,1) and wins on order, and it still LOSES to
   `:focus` and `[disabled]` at (0,4,1). */
