Make the notebook's Material 3 and layout widgets render through pythonx.compose #9
Description
What
Text, Button, Card, Column, Row, Spacer, Icon and DefaultIcons as UI.ipynb uses them, through the re-export rule (#8), with content lambdas.
Why
SPEC S5.2, S5.3, §8. The notebook is the specification (AGENTS.md §11). Open: notebook imports Column/Row/Spacer from material3 while Kotlin has them in foundation.layout (INTENT §4 question 2), and groups alignments as Alignment.Horizontal.End (SPEC §7).
Done when
Each widget has a render proof against PythonMultiplatform (pixels, not just composition), and the two spelling questions are decided and recorded in SPEC.

Grouped Alignment/Arrangement spelling landed via #45 (INTENT 5.3). Still open in #9: per-widget render proofs.

ksp-fixtures/notebook-e2e(#26, merged via #170, develop844cf291; SPEC B-10implementedon desktop). It ran 20 of 20 passed against this package'sdevelopwheel on 2026-10-04 (after python-multiplatform #146 and #168 and this repo's #88). The wheel is unpacked into the host's site-packages, and the tests requirepythonx.compose.__file__to be inside it. Recorded in SPEC via #96. Caveat: no CI workflow runs that module yet, so this is one local run.Done-when met. Each widget has a pixel render proof:
NotebookPracticeTest(13 tests) draws Text, Button, Card, Icon (DefaultIcons.Add), Column, Row (withArrangement.CenterandAlignment.Horizontal.End) and Spacer, each pixel-equal to the same composables drawn from Kotlin. Both spelling questions were decided and recorded: INTENT §5.2 (Column/Row/Spacer from material3, via aliases) and §5.3 (grouped alignments, #45). Still open elsewhere: the colour-scheme factories (SPEC S5.3,planned), pluscorner_radius/coloron Button and Card, which the E2E lists as gaps (Kotlin'sshape=/colors=).
