Update og image.

The old preview was a 1000x480 app screenshot that chat clients cropped and
rendered unreadable. The new card is rendered at 2400x1260 so iMessage shows it
across the full bubble width, and shipped as JPEG under 600 KB because WhatsApp
silently drops larger og:image files.

Claude-Session: https://claude.ai/code/session_01QeSrr5iYBXbi9WfaEtpq1W
sips produced a 225 KB file at PSNR 34.9 dB. cjpeg at quality 85 with 4:2:0
subsampling and progressive scans reaches 118 KB at PSNR 47.3 dB against the
same PNG master, so the card is both half the size and visibly cleaner.

The sRGB profile is embedded explicitly because cjpeg does not carry the
marker over from the PNG, and Apple clients tint an untagged JPEG with the
display profile, which would shift the brand red.
