## Round 1 (12:45-13:00, ~15 min)
Changed:
- Renderer: brows drawn over the bangs (vertex depth pulled 3 cm toward the camera, both passes), coloured a deep
  shade of the character's hair, alpha cut lowered so the stroke is fuller.
- Renderer: open mouth reads VRoid's mouth map as teeth / tongue / dark inside instead of one flat dark brown; a
  dark lip rim where the mouth meets the face (composite pass).
- Recipes: the ALL_* presets split into BRW/EYE/MTH parts so brows, eyes and mouth are weighted separately; open
  mouths smaller (joy MTH_Joy 0.6, surprised 0.55, A 0.75, E 0.85, O 0.8); brows added to smile/wink/smug.
Sheets: angry and sad now read from the brows alone (they were hidden under the bangs before). Joy/surprised/shout
read as open mouths with a rim. Problems: open mouths are all tongue pink (no dark inside, unlike the reference);
closed-mouth lines (neutral, smile, angry, wink, smug) are almost invisible; woman's brows heavy; smug reads sleepy;
surprised mouth a wide slit, not an O.

now a dilated dark line inside the mouth's UV window, so it bends with the mouth shapes); open mouth darker, with
the upper lip's shadow as a dark band at the top of the opening (not over the teeth); recipes: sad MTH 0.8,
surprised MTH_O 0.5, smug lidded + slight one-eye squint + lowered brows + closed smile.
Sheets: the biggest single gain. Angry's frown, smile's curve, wink and smug's closed smiles now read at sheet
size, as in the reference. 30 degree tiles: mouths hold; the far brow is still lost under the bangs on the woman.
Surprised mouth still a wide slit; dark band takes too much of small mouths; brows blunt and heavy.

## Round 4 (13:14-13:23, ~9 min, page only, no rebuild)
Changed: the closed-mouth line tapers toward its corners (a brush stroke, as the reference's lines thin out);
brows take a soft rim (hair colour mixed in where the texture's alpha is low), so they read less like flat cut-outs.
Sheets: small but real gain; neutral looks calmer, brows lighter. Best round: FINAL_* are round 4.

## Eyebrow decision: draw the brows over the bangs
Yes, for our characters. Both test bodies (and most of our VRoid hair) have bangs that sit on or below the brow
line, so with the brows hidden every brow-led expression (angry, sad, surprised, shout, smug) collapsed into the
neutral face; the before sheet shows it. The reference rigs can keep their brows under the hair only because
their bangs are cut above the brows, i.e. they solve it with the haircut. We can't recut every hairstyle, and our
faces are small on screen in the tactics view, where the brow is the strongest single cue. Drawing them over is
also a common anime convention. Implementation: the brow mesh's depth is pulled 5 cm toward the camera in the
vertex shader (`uFront`), in both the info and colour passes, so it beats the bangs (1-4 cm in front of the
forehead) but not the far side of the head at large yaw or anything further out. 3 cm was not enough at 30
degrees. Colour: a deep shade of the character's hair, so blond brows still contrast on blond hair.
Risk: a helmet brim within 5 cm of the brow would also be drawn under the brows; not checked (the helmet rows
are outside this benchmark's two bodies).

## Still weak
- Smug has no one-sided smirk: VRoid has no left/right mouth shapes; it reads as lidded + closed smile.
- The woman's bangs still cut across her eyes, so eye-shape changes (angry squint, sad droop) read weaker than
  in the reference; the brows carry those expressions.
- The open-mouth colours come from thresholds on VRoid's mouth map (green channel / brightness); a different
  VRoid mouth texture could split teeth/tongue differently.
- The closed-mouth ink uses a fixed UV window (0.38-0.62 x 0.68-0.84) of the shared VRoid face layout.
- Sad uses a small open mouth (MTH_Sorrow) where the reference uses a closed frown.
- Brows are still slightly heavy on the woman; nose is still only a faint grey mark.

End: 13:24 PST. 4 rounds, ~41 minutes.

FINAL_woman.png, FINAL_youth.png (both round 4) and NOTES.md are in work/a.\n\nWhat changed:\n- **Brows over the bangs.** I chose to draw them on top of the hair. Both bodies' bangs hid the brows, so angry, sad, surprised and shout collapsed into neutral. The reference keeps its brows visible by cutting the bangs above them, which we can't do for every hairstyle. The brow depth is pulled 5 cm toward the camera in both passes; 3 cm still lost the far brow at 30°. The colour is a deep shade of the hair with a soft rim.\n- **Closed mouth.** It was a faint line from VRoid's face texture. It is now inked, widened and thinner at the corners, so frowns and smiles read.\n- **Open mouth.** It was a flat dark blob. It now has teeth, tongue and a dark inside, a lip outline and a shadow under the upper lip.\n- **Recipes.** The full-face presets are split into separate brow, eye and mouth weights, with smaller open mouths and a round surprise. They are committed as `review/vroid-02/expr_recipes.txt`.\n\nWhat still reads weakly:\n- Smug has no one-sided smirk; VRoid has no left or right mouth shapes.\n- The woman's bangs cross her eyes, so the eye shapes count for less than in the reference.\n- Not checked: a helmet brim within 5 cm of the brows would be drawn under them.",
