2 * Sequoia Subscribe - An AT Protocol-powered subscribe component
3 *
4 * A self-contained Web Component that lets users subscribe to a publication
5 * via the AT Protocol by creating a site.standard.graph.subscription record.
6 *
7 * Usage:
8 * <sequoia-subscribe></sequoia-subscribe>
9 *
10 * The component resolves the publication AT URI from the host site's
11 * /.well-known/site.standard.publication endpoint.
12 *
13 * Attributes:
14 * - publication-uri: Override the publication AT URI (optional)
15 * - callback-uri: Redirect URI after OAuth authentication (default: "https://sequoia.pub/subscribe")
16 * - button-type: Branding style — "sequoia" (default), "bluesky", "blacksky", "atmosphere", or "plain"
17 * - label: Override the subscribe button label text
18 * - unsubscribe-label: Override the unsubscribe button label text
19 * - hide: Set to "auto" to hide if no publication URI is detected
20 *
21 * CSS Custom Properties:
22 * - --sequoia-fg-color: Text color (default: #1f2937)
23 * - --sequoia-bg-color: Background color (default: #ffffff)
24 * - --sequoia-border-color: Border color (default: #e5e7eb)
25 * - --sequoia-accent-color: Accent/button color (default: #2563eb)
26 * - --sequoia-secondary-color: Secondary text color (default: #6b7280)
27 * - --sequoia-border-radius: Border radius (default: 8px)
28 * - --sequoia-icon-display: Icon display mode (default: inline-block) — set to "none" to hide
29 *
30 * Events:
31 * - sequoia-subscribed: Fired when the subscription is created successfully.
32 * detail: { publicationUri: string, recordUri: string }
33 * - sequoia-subscribe-error: Fired when the subscription fails.
