Name what a component tag takes in place of each Blade directive

The guard said a directive does not compile inside a component tag but
not what to write instead, and the skill's note said only "use {{ }}".
SealShare's two-factor challenge had @js in an x-data on <x-stack>, and
its implementer had to work out {{ Js::from() }} from Laravel's source.
Each message now names the form: Js::from for @js, json_encode for
@json, Arr::toCssClasses and toCssStyles for @class and @style,
$wire.entangle for @entangle, a bound attribute for @disabled and its
kin, and a prop, an echo or a plain element for control structures
(plan step 46).

+- Blade directives do not compile inside a component tag's attributes: `<x-foo x-show="ok(@js($value))">` reaches the browser as literal text. On a component tag use `{{ }}` and `:prop` bindings — `@js($value)` is `{{ \Illuminate\Support\Js::from($value) }}`, `@class([...])` is `:class="\Illuminate\Support\Arr::toCssClasses([...])"` — or put the Alpine on a plain element inside the slot. `DesignGuard` names the form for each directive.
 - Never pass `hidden`, a display utility or a position (`absolute`, `relative`) to a component: it is merged beside the component's own and whichever Tailwind emits last wins. Wrap the component in an element that carries it. A variant that only hides (`max-medium:hidden`) is safe.
 - `$attributes->wire('model')->value()` is `false`, not `null`, when there is no `wire:model`, and `filled(false)` is true. Normalise with `?: null`.
 - End every statement in a multi-line Alpine attribute with `;`: an inline `@if … @endif` inside it swallows the newline after it.
