CRITICAL — COMPOSER RIGHT CLUSTER (this is where one-shot gens fail)
════════════════════════════════════════════════════════════════
The bottom of the prompt card is ONE toolbar row. Left: three chips. Right: “Sonnet 4.5”, paperclip, orange send circle.
DO NOT do any of the following (these are the usual mistakes):
- wrapping model + attach + send in a flex row with align-items:center
- giving the send button the same height as the chips
- vertically centering the send circle with the “Sonnet 4.5” text
- putting the send button on its own row or in the card’s vertical center
- adding padding/min-size around the paperclip (it is a raw SVG, not a padded icon button)
- using gap: 8px / 12px / 16px guesses between those three controls
DESKTOP MUST use absolute coordinates inside the toolbar, copied from the measured 1560×1008 frame.
Card (absolute frame coords): x=425, y=413, w=708, h=143, radius=26
Toolbar strip (.tools) inside the card:
left = (444 − 425) = 19u from card left
top = (505 − 413) = 92u from card top
height = 30u ← this is the CHIP row height
right ≈ card right (formula: right: calc((425 + 708 − 1134)*var(--u)) which is −1u)
Chips fill that 30u-tall strip. The send circle is TALLER than the chips and is NOT centered on them.
RIGHT CLUSTER (.right):
position:absolute; inset:0; pointer-events:none
each child: position:absolute; pointer-events:auto
(left offsets are relative to .tools, whose left edge is frame-x 444)
MODEL “Sonnet 4.5” + chevron
left: (955 − 444 − 0.8) = 510.2u
top: 15.5u
font-size: 10.4u, weight 400, color #98999C, line-height 1
display:inline-flex; align-items:center; gap: 6.2u
chevron SVG width: 6.8u
The 10.4u text sits in the LOWER-MIDDLE of the 30u chip row (top 15.5 + height 10.4 = 25.9, so it sits above the chip baseline, not vertically centered with the 35u send).
ATTACH paperclip
left: (1043.15 − 444) = 599.15u
top: (515.14 − 505) = 10.14u
color #A9AAAD
SVG width: 19.79u (no button padding, no background, no 32px hit box)
hover color #fff
SEND circle
left: (1084 − 444) = 640u
top: (507 − 505) = 2u
size: 35 × 35u, border-radius 50%
So: send top is 2u below the chip-row top; send bottom is at 2+35=37u, which HANGS 7u BELOW the 30u chip row.
Right padding: card right (1133) − send right (1084+35=1119) = 14u from the card’s inner right edge.
Horizontal gaps (do not invent others):
attach right ≈ 599.15+19.79 = 618.94u
send left = 640u
gap attach→send ≈ 21.06u
model starts at 510.2u; leave the natural width of “Sonnet 4.5” + 6.2u + chevron; do not stretch it.
VISUAL CHECK (desktop screenshot):
All three chips, the model label, the paperclip, and the send circle share one horizontal band near the BOTTOM of the glass card.
Placeholder text is a separate band near the TOP of the card (33u from card top). Two bands, not one.
The orange circle is the largest control on that band. Chips are 30u tall pills. Send is a 35u circle that slightly overshoots the chip row downward.
“Sonnet 4.5” is small muted text sitting left of the paperclip, vertically aligned to the chip TEXT, not to the send circle’s center.
Paperclip sits between the model label and the send circle, slightly higher than the model text, lower than the send’s top.
TABLET (600–1180 wide AND height ≥ 600) is the ONLY place the right cluster becomes flex:
.right { position:static; display:flex; align-items:center; margin-left:auto; gap:0 }
.right > * { position:static }
.attach { margin-left: clamp(9px, 1.4vw, 20px) }
.send { margin-left: clamp(9px, 1.3vw, 18px); width/height: clamp(32px, 3.5vw, 38px) }
Toolbar stays ONE ROW: chips left, controls right. Do not wrap the send onto a second row.
PHONE (max-width 599, or height < 600 with width ≤ 1180):
.tools { flex-direction:column; align-items:stretch; gap:12px }
chips wrap on row 1
.right { position:static; display:flex; align-items:center; justify-content:flex-start }
.attach { margin-left:auto } ← paperclip + send hug the right; model stays left
.send { margin-left:14px; width:40px; height:40px }
Still not a centered send. Model left, attach+send right, same second row.

Do not add a second section below the fold.
Desktop composer: absolute toolbar. Right cluster is NOT a flex-centered group.
