CedricandClaude Opus 5.5 1deb2a43d0 App icon and a lavender Stretching palette
A lotus inside a dry-brush ensō, with a small plate in the gap and a small
barbell as the lifting hint. Drawn by tools/icon/make_icon.py and wired up
with flutter_launcher_icons; the launch screen uses the icon's lavender.
Stretching Mode moves from sage/teal to the icon's lavender and violet.

# ADR 0007 — App icon: a lotus in a Zen circle, with a hint of lifting
Status: Accepted (2026-10-29)
1. **Motif**: a lotus inside an ensō (Zen brush circle). Yoga and calm lead; lifting is only a hint:
a small weight plate floating in the circle's open gap, and a small barbell under the lotus.
2. **Brush**: the ensō is painted counter-clockwise from the top, with its gap at the upper right.
It starts round and solid with calm, nearly smooth edges, then runs dry: pale streaks open inside
the stroke and the bristles give out at different points, so the tail frays out close to the plate.
The circle is never closed.
3. **Colours**: a calm purple palette: lavender mist ground `#F1EEF6`, muted violet `#6B5B95` for the
ensō and the lotus's centre petal, light violet `#A496C8` for the side petals, and a soft apricot
`#E98A6F` only for the plate and the barbell.
4. **Stretching follows the icon**: Stretching Mode's palette moved from sage/teal to the same lavender
and violet, so the app and its icon match. Workout keeps its dark ember design.
5. **Style**: flat shapes, no text, no gradients or outlines.
6. **Format**: Android adaptive icon (foreground on a solid lavender background, masked by the launcher)
plus a legacy square PNG, wired up with `flutter_launcher_icons` as in CookIT.
7. **Launch screen**: the Android launch background uses the same lavender mist as the icon.
The icon is generated by `tools/icon/make_icon.py` (seeded, so it redraws identically): run it, then
`dart run flutter_launcher_icons`. Rejected along the way: a dumbbell or barbell as the main element,
a plate closing the circle's gap, a seated figure, and heavier, more textured brush strokes.
