**Composition** : Horizontal 800×500 canvas. Diagonal composition: lower-left contains a hand+agenda, upper-right contains a moon and starry element. Generous negative space in the corners.

**Subject** : A stylized hand (only the hand, no arm past the wrist) holding an open journal/agenda. The agenda is a simple rectangular booklet, opened flat. On its pages: a grid of small squares representing sleep tracking (light navy squares filled to varying degrees, some empty). The hand is in cream skin tone, minimal detail — just the outline and one line for the thumb.

**Key visual elements** :
- Upper-right : a crescent moon in cream (#FFF8E7) with 2 small stars in teal (#2A9D8F)
- The agenda pages show subtle sleep-tracking grid pattern (rounded squares in navy #050D1A at varying opacity)
- A single thin teal line connects loosely the moon area to the agenda, suggesting "tracking one's nights"

**Style** : Flat vector editorial illustration. In the style of The New Yorker spot illustrations. Clean confident lines, minimal shading.

**Color palette** (strict) : navy #050D1A (agenda outline, hair-if-any), warm cream #FFF8E7 (skin, moon, agenda background), teal #2A9D8F (accent stars, connecting line), primary #1B4F8A (subtle grid marks on agenda pages). White or transparent background.

**Mood** : Confident, curious, sober. The intellectual side of sleep recovery.

**Negative prompt** : NO photorealism, NO detailed hand anatomy, NO fingernails detail, NO 3D, NO pen/pencil (would look too specific), NO clock, NO calendar with numbers, NO English text, NO French text visible in the agenda (just abstract grid), NO drop shadows.
