@pie-players/pie-tool-calculator-shared

Provider-neutral Svelte surfaces for PIE calculator tools. This package owns calculator lifecycle, toolkit-context wiring, visibility, resizing, focus, loading/error presentation, and the inline toggle. It does not load or name a calculator vendor.

The provider-neutral registration entry owns the stable generic element:

import "@pie-players/pie-tool-calculator-shared/calculator-element";

It registers <pie-tool-calculator> with the existing Desmos default. The Desmos-named package remains a compatibility entry for the same guarded registration.

Provider packages wrap these components in their own custom-element tags and supply a default provider id. Applications normally install a provider package, not this package directly, unless they intentionally want the generic element.

The shared inline trigger owns these component-level active-state theme hooks:

• --pie-tool-trigger-active-background
• --pie-tool-trigger-active-border-color
• --pie-tool-trigger-active-color

Its resting and hover fills resolve through the button tokens — --pie-button-background-color then --pie-button-bg, and --pie-button-hover-background-color then --pie-button-hover-bg. Every base theme and colour scheme sets those opaque. --pie-background is the page token and the base light theme ships it transparent, so it does not reach this fill.

Vendor wrappers inherit the same WCAG-focused focus, pressed-state, reduced motion, and touch-target behavior.
