DESIGN-NOTE — AI Friday

The scene

7:15 p.m. on a Friday in early October. The sun went down at 6:49, so the west end of the street still has satsuma in it and everything else has already gone blue. A double shotgun in the Bywater, chalky pale-yellow clapboard, shutter-green shutters, a deep full-width porch on four turned columns. The beadboard ceiling is painted haint blue. One bare warm bulb just came on. Four people on the porch, mid-conversation, one of them laughing. A round enamel table with a sweating pitcher of iced tea, mismatched glasses, a bowl of satsumas, a notebook.

And one empty chair, turned slightly out toward the steps.

That chair is the whole brief. You're invited, it's happening, it's here.

What the seed decided

A 192-character random string set the calls the brief left open. The readings I used:

Time of evening. The digit stream carries 1915 — 19:15. Twenty-six minutes after sunset on October 2 in New Orleans. Golden hour has tipped; blue hour has landed but hasn't finished. Every image is lit at that exact minute.
Type scale. The digits sum to 142 → 1.414 (√2) for the display steps, and the literal run 1125 → 1.125 for the text steps. A dual-ratio scale: quiet through the reading sizes, dramatic at the top.
Circles. The digit stream opens 314. The porch table is round, and it's the only round thing on the page.
Three doubled letters (pp, JJ, zz) → exactly three photographs beyond the hero. No more. Empty space is fine on a porch.
House. A double shotgun rather than a single: two front doors, one shared porch. The building itself is the argument that there's room for one more.

Colour — haint blue is the ground, not an accent

The obvious move is a cream page with a warm accent. That's the default, and it would make haint blue a decorative swatch. Instead the page itself is the porch ceiling: pale haint blue is the field you read on top of, top to bottom, and the warm colours are the light falling on it.

token	value	what it is
`--haint`	pale chalky blue	the ceiling. The page ground.
`--haint-deep`	dusty blue	rules, quiet type, the second button
`--porch-paint`	warm chalky off-white	clapboard. Reading panels and the invitation card.
`--satsuma`	ripe orange	the sky at 7:15 and the one primary action
`--shutter`	dark blue-green	shutter paint. All body type, and the night footer.
`--cypress`	warm mid-brown	porch decking. Hairlines, captions, small print.

No black, no pure white. Nothing purple, gold, or Mardi Gras. Exact hexes get sampled off the hero once it exists — the photo sets the palette, not the other way around.

Type

Two families, six styles total. Nothing technical, nothing monospaced.

Newsreader for display and for the invitation. A low-contrast bookish serif with a real italic — it reads like a printed invitation, not like a fashion masthead. Set light and large. The italic carries the asides.
Work Sans for body, labels, and buttons. Plain, friendly, unfussy. The voice of somebody talking to you on a step, not a brand talking at you.

Scale: 17px base. Text 13.4 / 15.1 / 17 / 19.1 (×1.125). Display 24 / 34 / 48 / 68 / 96 (×1.414). Spacing: 4px base — 4, 8, 12, 16, 24, 32, 48, 64, 96, 144. Radius: 3px everywhere. Painted wood and paper have edges. No pills, no glow, no cards-within-cards.

The signature: the invitation card

One memorable object. Sitting over the hero photograph is a small warm-white card with the date set large in Newsreader, the time and place underneath, and the two actions on it. It reads as a physical thing somebody left on the empty chair for you. It's where all the boldness is spent; everything below it is quiet.

How the sections sit on the porch

The page is a slow walk from the sidewalk to the door.

Four photographs total: the porch, the table, the ceiling, the empty chair at the end of the night. All photographic, all lit at 7:15, all generated — no CSS standing in for light or surface.

Voice

Hospitality, not registration. "Pull up a chair," not "Register now." "Come by anytime," not "Join our community." Short lines, plain verbs, second person. Never explains what AI is. Never suggests you need to already know anything.

Anti-goals, held

No dark mode, no monospace, no terminal. No feature grid, no pricing rhythm, no eyebrow labels, no gradients, no glow. No beads, no fleur-de-lis, no jazz, no masks, no purple-green-gold, no Bourbon Street, no French Quarter. This is a house somebody lives in, on a street where people know each other.
