Unable to override variables using new Sass modules

Versions:

"sass-embedded": "^1.89.2",
"vite": "^6.3.5",
"@coreui/coreui-pro": "^5.14.2"

Following the tutorial on https://coreui.io/bootstrap/docs/customize/sass/ I've migrated from @import to @use statements when including CoreUI Pro in my application.
Unfortunately it results in the error seen on the screenshot below.
The content of the file (that is @imported in my app.scss) that includes CoreUI Pro:

@use '@coreui/coreui-pro/scss/coreui' with (
    // Options
    $enable-deprecation-messages: false,

    $enable-dark-mode: false,
    $enable-shadows: true,
    $enable-gradients: false,
    $enable-rounded: true,

    // Typography
    $font-family-sans-serif: "'Poppins', sans-serif",

    // Colors
    $blue: #26ace2,
    $red: #e1001e,

    $primary: #26ace2,
    $danger: #e1001e,

    $primary-bg-subtle: #e9f7fc,

    // Body
    $body-bg: white,
    $body-color: #212326,

    // Accordion
    $accordion-button-bg: #e9f7fc,
    $accordion-button-active-bg: #e9f7fc,

    // Spinner
    $spinner-vertical-align: -.3em,

    // Buttons
    $btn-hover-color: white,
);

P.S. The previous setup was like this:

// CoreUI variables override
@import 'variables';

// Include CoreUI
@import '@coreui/coreui-pro/scss/coreui';

This file was later included in app.scss. After updating to @core/coreui-pro v5.14.0 it is failing, since the decision to migrate.

Start by reproducing the failure with sass-embedded 1.89.2, Vite 6.3.5, and CoreUI Pro 5.14.2 using the shown app.scss, variables, and @use configuration. Inspect how the CoreUI Sass module exposes configurable variables and compare it with the previous @import setup. Done means the documented module setup compiles and the listed variable overrides take effect.
