Pull request overview

Refactors the Android sample app UI to reflect UI/UX feedback, including updated navigation affordances, disabled/“coming soon” flows, and minor styling adjustments.

Changes:

• Updates sign-in and dashboard UI behavior (default selection, disabling certain destinations, “coming soon” affordances).
• Adds “enabled/disabled” styling to reusable card components (grid cards and factor cards).
• Tweaks profile/theme-related UI and prepares first/last name prefilling for the “Update Full Name” screen.

Hardcoding a specific Auth0 client ID/domain in the sample app resource file makes the repo tenant-specific and conflicts with the setup instructions in README.md (which uses placeholders like YOUR_CLIENT_ID/YOUR_DOMAIN). Consider reverting these to placeholders and loading developer-specific values from a local (uncommitted) source such as gradle.properties, local.properties, or an example strings file committed separately.

Suggested change

	<string name="com_auth0_client_id">0uEJeUx6dLhVwTEya6PApVDvZ6fwkZyO</string>
	<string name="com_auth0_domain">p-mathew.us.auth0.com</string>
	<string name="com_auth0_client_id">YOUR_CLIENT_ID</string>
	<string name="com_auth0_domain">YOUR_DOMAIN</string>

selectedOption now defaults to Hosted, which means the Continue button is enabled immediately. The KDoc above still states the button is disabled until a card is selected; either update the documentation to reflect the new default behavior or restore the previous null default so the UI matches the documented flow.

The new enabled parameter only changes alpha; the Card remains clickable and will still be announced as enabled by accessibility services. If enabled is meant to disable interaction, wire it into the click handling (e.g., pass enabled to the clickable/Card API and/or omit onClick when disabled). If it’s only meant to visually indicate “coming soon”, consider renaming the parameter (e.g., dimmed/inactive) to avoid misleading API semantics.

Suggested change

	onClick = onClick,
	onClick = onClick,
	enabled = enabled,

Splitting the full name using a literal single-space delimiter can leave leading spaces in the last name when the display name contains multiple spaces (e.g., "John Doe"), and won’t handle other whitespace characters. Consider splitting on a whitespace regex and trimming the resulting parts before passing them into UpdateFullNameScreen.

Suggested change

	val nameParts = userProfile.name.trim().split(" ", limit = 2)
	val nameParts = userProfile.name
	.trim()
	.split("\\s+".toRegex(), limit = 2)
	.map { it.trim() }
