Indeterminate progress indicator. Three visual variants

(<code>ring</code>, <code>dots</code>, <code>bars</code>), five sizes, eight color accents,

and an optional inline label. Eidos-native: no semantic events, no soma split — the morfo

declares two parts (Provider + decorative Track). Use
|

<a href="/uix/components/progress"><Progress></a> instead when you have a known

Spinner declares <strong>no semantic events</strong>. The loading state announces only
|
|
|
through ARIA — there is no commit/emerge/shift to react to. Mount the spinner when work
|
|
|
starts; unmount when it ends.

|
|

|
<p data-uix-section-desc>
|
|
|
If you need a perceptual cue when the work starts or finishes, attach it to the parent
|
|
|
action (the form submission that triggered the fetch, the route navigation that opened
|
|
|
the page) — not to Spinner.

Recipe lives in <code>src/uix/eidos/components/spinner/spinner.css</code>. All three

variants share private tokens (<code>--_spinner-size</code>,
|

|
<code>--_spinner-color</code>, <code>--_spinner-track</code>); each variant adds its own
|
|

keyframes block.
