feat(designsystem): redesign the late-night sleep timer prompt - #1241
The late-night sleep timer prompt is redesigned in Material 3 Expressive, in the theme's colours: a night-sky band with a turning scalloped moon and twinkling stars, the times as a connected button group, and a confirmation that says when playback will pause.
Motivation
The prompt was a fixed near-black island in every theme, with plain chips and a fade-and-scale entrance. It now follows light, dark and every theme preset, and its motion matches the rest of the app.
What changed
SleepTimerPopup (:core:designsystem):
a surfaceContainerHigh card that drops in from the top, with a primaryContainer night-sky band: a slowly turning MaterialShapes.Cookie9Sided moon in primary, three twinkling stars, the question and Dismiss
the times as a connected button group in secondaryContainer (the pressed one widens and rounds), End of episode in primaryContainer
a pick sets the timer at once and fills its button in primary; the choices fold away, the moon sets behind the band and a tertiary badge rises in its place with the time ("45 min", "1 hr", or an end-of-episode mark), beside "Pausing in 45 min" and "Good night." (a polite live region); the prompt leaves three seconds after the pick
each showing keeps its own pick (saveable, so a rotation keeps the confirmation), and a prompt shown again starts afresh
the 420dp width cap now applies on wide windows; the card was filling the whole width before
copy moved to string resources
SleepPromptMotion: the entrance and confirmation as pure functions of two clocks, read while drawing; with system animations off every step shows its final state and nothing twinkles or turns.
The public API is unchanged, so AppPlaybackNotices needs no change.
Behavior & compatibility
Same trigger (once per night window), same options, same dismiss reasons and analytics (Manual, Timeout, Confirmation).
The confirmation now stays about three seconds (was 1.8) so it can be read.
No API or payload changes.

What changes in the user’s life:
The late-night sleep timer prompt looks like part of boxlore in their own theme colours, and after picking a time they see when playback will pause.

Changed
SleepTimerPopup redesigned in Material 3 Expressive theme roles: a night-sky band with a Cookie9Sided moon, a connected button group for the times, and a confirmation badge with the picked time; motion in SleepPromptMotion; copy in string resources; the 420dp width cap now applies.
Listener notes (required for user-impact changes)
Listener notes already cover this change
release-notes/upcoming.md: one Improved line for the new prompt.
Test plan
Installed on a phone
:core:designsystem JVM tests (245), ktlint and detekt pass locally
SleepPromptMotionTest: the entrance, the confirmation (the badge rising before the moon has gone, everything settled well before the prompt leaves), the stars' twinkle and the badge's hours/minutes/end-of-episode rule
SleepTimerPopupTest: every option shown, a pick setting the timer once and confirming before Confirmation, Dismiss and the timeout, the confirmation surviving state restoration, a prompt shown again after a pick starting afresh (fails on the earlier state handling), a prompt hidden mid-confirmation reporting once, and the width filling a 360dp window and capping at 420dp on an 840dp one through window changes both ways
Local captures in both themes compared with the design boards
Required checks are green before merge
Notes (optional)
Adaptive states: phone width, 840dp and the transitions between them mid-confirmation are covered by the JVM test; the prompt is a top overlay with no other window-dependent layout. Device check so far: phone.
To see it on a device: Library, long-press Settings, Debug, sleep-prompt testing.
The prompt now uses the theme's colours instead of a fixed near-black
island: a night-sky band with a slowly turning scalloped moon and
twinkling stars, the times as a connected button group and End of
episode below. A pick sets the timer at once; the choices fold away,
the moon sets and a badge with the chosen time rises in its place,
beside when playback will pause.
Each showing keeps its own pick, so a prompt shown again starts afresh,
and the 420dp width cap now applies on wide windows.
Added an animated, night-sky sleep-timer prompt with duration and end-of-episode options.
After selecting an option, see a confirmation of when playback will pause. The prompt closes after confirmation or automatically if left untouched.
The prompt adapts to window size and respects system animation settings.
Documentation
Added guidance on the prompt’s behavior, accessibility announcement, and state restoration.
SleepTimerPopup now displays an animated night-sky card with timer choices and a confirmation state. Selection, timeout, manual dismissal, reduced-motion behavior, and badge formatting are covered by implementation changes, tests, localized strings, and documentation.

Summary
Motion calculations and timing core/designsystem/src/main/java/cx/aswin/boxlore/core/designsystem/components/SleepPromptMotion.kt, core/designsystem/src/test/java/cx/aswin/boxlore/core/designsystem/components/SleepPromptMotionTest.kt
Adds entrance and confirmation pose calculations, star twinkle values, and timing constants. Tests check motion values and badge classification.
Popup state and selection flow core/designsystem/src/main/java/cx/aswin/boxlore/core/designsystem/components/SleepTimerPopup.kt, core/designsystem/README.md, core/designsystem/src/test/java/cx/aswin/boxlore/core/designsystem/components/SleepTimerPopupTest.kt
The popup saves selection and confirmation state while shown, accepts one selection, and reports manual, timeout, or confirmation dismissal. Tests cover selection, dismissal, reopening, state restoration, and width changes.
Night-sky presentation and timer labels core/designsystem/src/main/java/cx/aswin/boxlore/core/designsystem/components/SleepTimerPopup.kt, core/designsystem/src/main/res/values/strings.xml, core/designsystem/src/test/java/cx/aswin/boxlore/core/designsystem/components/SleepTimerPopupTest.kt, core/designsystem/README.md, release-notes/upcoming.md
Adds the animated night-sky band, timer choices, and badge labels. Localized strings and tests cover episode-end selection and responsive layout. The README and release note describe the prompt and test coverage.

Merge Risk: Low · previous review bd120
The redesigned sleep prompt works, but a Dismiss tap after picking a time or during the exit window can record extra dismissal events and skew analytics. One motion test may also be flaky. These are small, localized fixes that can be handled before or shortly after merge.

@core/designsystem/src/main/java/cx/aswin/boxlore/core/designsystem/components/SleepTimerPopup.kt:
- Line 279: Update the question and choices nodes in the SleepTimerPopup flow to
remove their accessibility semantics once picked is non-null. Apply the change
to both the question Column identified by SleepPromptMotion.questionAlpha and
the choices Column identified by SleepPromptMotion.choicesAlpha, while
preserving their existing fade and fold animations.
- Line 161: Update the SleepTimerPopup Dismiss handler to report Manual only
when picked is null; after a pick, route dismissal through Confirmation once,
using confirmed to prevent duplicate reports. Update the README sentence
describing Dismiss behavior to reflect this distinction.
- Line 137: Update the timeout logic in SleepTimerPopup’s LaunchedEffect(picked)
to read the latest visible value via rememberUpdatedState, rather than the value
captured when the effect launched. Only call dismiss with Timeout when the popup
is still visible, preserving the existing effect and dismissal behavior.
Review comments at
@core/designsystem/src/test/java/cx/aswin/boxlore/core/designsystem/components/SleepPromptMotionTest.kt:
- Around line 57-59: Update the phase used in the star-twinkle distinctness
assertion in SleepPromptMotionTest so SleepPromptMotion.twinkle produces three
clearly different brightness values, avoiding reliance on floating-point
rounding; keep the distinctness assertion unchanged.
Review comments at
@core/designsystem/src/test/java/cx/aswin/boxlore/core/designsystem/components/SleepTimerPopupTest.kt:
- Around line 116-136: Add JVM tests alongside the existing SleepTimerPopup
tests for reduced motion and dismissal during confirmation. Set the animator
duration scale to zero before `show()`, verify the question and choices appear
immediately and a pick displays “Pausing in …” without clock advancement, then
restore the scale even if assertions fail. Add a test that picks a timer value,
taps “Dismiss,” and verifies exactly one dismissal reason is reported.
