closes#29
All eight illustrations are in the app, every onboarding step has art for the
first time, and the theme swap is resource resolution rather than a branch:
drawable/ and drawable-night/, so Android picks the asset and the artwork follows
a device theme change with nothing of ours running.
NOT VECTORS, AND THE ISSUE WAS WRONG TO ASK FOR THEM
#29 called for a redraw as Compose vector paths taking colour from theme tokens.
That is right for artwork that does not exist yet and wrong for gradient
landscapes with glow and depth — there is no honest VectorDrawable of one, and
the attempt loses the drawing or produces path soup slower than the image. §42
objects to *unnecessary* raster, which this is not.
The cost was never measured before it was argued about: all sixteen files at the
height they are actually drawn at come to 130 KB. Release APK 1.90 -> 2.03 MB.
WHAT ONLY A DEVICE SHOWED
Each drawing is composed as a card with its own rounded corner painted in, so the
pixels outside that curve are the card's own backdrop — near-black in the dark
set. Rendered unclipped, every illustration showed four notches against the app
background. Illustration() now clips just inside the painted curve.
WHAT STAYED A VECTOR
The calendar markers and CycleProgressMark, because they are drawn from data — a
marker's shape is what a day is, and the progress arc is where the user stands in
their cycle. CycleProgressMark moves from Illustrations.kt to CycleMarkers.kt so
the file layout carries that boundary.
Sized by height rather than a square box: the set has no common aspect ratio, and
height is the dimension that decides whether the primary button stays on screen.
Steps 3 and 6 take 104dp because they carry three buttons and three option cards;
verified by driving all seven steps, not by reasoning about it.
OnboardingPreviews.kt now has one entry per illustration, because a missing
drawable-night asset is invisible in light mode.
Driven end to end on PeriodMinSdk26 in both themes, no crash. ./gradlew check,
schema-guard and doc-claims all pass.
