X Page

x-page: X / Twitter profile visuals

Goal: produce the PNG assets of an X (Twitter) profile at the official dimensions (source: X help, "customize your profile"), aligned with the guidelines. Two possible visuals, independent of each other:

• profile photo: the brand, 400×400, cropped to a circle;
• header / banner: 1500×500 (3:1).

This is a specialization of new-template with the X constraints hard-coded. Same conventions: the Template contract, assets through brand(), fonts discovered in fonts/, export default ... satisfies Template.

0. Prerequisites (blocking)

The chain project -> template folder -> guidelines must exist:

• Resolve <project> (from the arguments, otherwise ask).
• Check templates/<project>/ and brands/<project>/brand.md.
• Missing guidelines or project -> STOP: ask for /new-project <project> first. No visual without guidelines (CLAUDE.md rule).

1. Frame it

• Which visual(s)? Ask: profile, header, or both.
• Default slugs: x-profile (400×400), x-header (1500×500). Check that the target .tsx does not exist.
• Read brands/<project>/brand.md: palette, type, the logo / favicon variants and their rules depending on the background, and the don'ts.
• If the project already holds a .tsx, read it as a style reference.

2. X constraints (to respect)

• Format: PNG or JPG. Opaque background. X documents no maximum weight for these two visuals (the official 5 MB applies to tweet images).
• Profile: square, brand centered, nothing important in the corners (displayed as a circle). 400×400 is the official size; scale: 2 is advised for crispness. For an organization, prefer the mark alone / the favicon over the wordmark, which is illegible when small. Follow brand.md.
• Header (1500×500): on mobile, X crops the sides, so keep the important content centered, with comfortable side margins.
• Dead zone bottom left (profile photo): on the profile page, the avatar covers the bottom left of the header, so any text or logo falling there is hidden. Leave it clear: left margin ~2.5 % of the width, box ~23 % W × ~35 % H anchored bottom left. On 1500×500: roughly x 38→388, y 325→500.

3. Write the template(s)

templates/<project>/<slug>.tsx, with colors as constants taken from the guidelines (invent nothing). Pick SIZE according to the visual:

import type { ReactNode } from "react";
import { brand, type Template } from "brand-artisan";
// import { readFile } from "node:fs/promises"; // if you load the mark

// Pick according to the visual:
const SIZE = { width: 400, height: 400 };   // Profile 1:1 (scale:2 advised)
// const SIZE = { width: 1500, height: 500 };  // Header 3:1

// <Project> guideline palette (from brands/<project>/brand.md).
const INK = "#......";

function render(): ReactNode {
	return (
		<div style={{ width: "100%", height: "100%", display: "flex", /* ... */ backgroundColor: INK }}>
			{/* brand centered (profile) OR lockup + standfirst centered (header) */}
		</div>
	);
}

export default { size: SIZE, title: "<Human title>", render } satisfies Template;

Shared conventions: assets through brand("<project>/..."), fonts discovered in fonts/; a missing font -> the "missing font" appendix in new-template, never silently.

4. Verify

• npm run typecheck -> green.
• npm run build -> writes out/<project>/<slug>.png.
• Check each PNG: exact dimensions (400×400 / 1500×500), opaque background.
• Profile: check the circular crop (nothing in the corners).
• Header: nothing important in the bottom-left corner (profile photo) nor too close to the side edges (mobile crop).
• Preview: npm run dev then /<project>/<slug>.

Success criterion: PNGs at X's exact dimensions, opaque, brand centered and legible for the profile, safe area respected for the header, and using only colors and type from brand.md.
