Source for website/public/og.png (1200x630).
|
|
Render with: npm run og (website/)
|
|
|
|
This card is a portrait of the page it links to, so every value here is lifted
|
|
from src/pages/index.astro rather than invented: the --paper ground, the two
|
|
diagonal green ambient washes, the grain that keeps them from banding, Public Sans
|
|
for the statement, JetBrains Mono for the footer, and the 100deg
|
|
#cdead9 -> #2f8f5c signature on "future." Change the site's palette or hero and
|
|
this file has to follow, or the card goes stale again.
|
|
|
|
Legibility rule (enforced by render-og.mjs): a social card is shown as small as
|
|
~320px wide (27% scale), so nothing here is smaller than 30px, no line reaches
|
|
the 72px padding, and there are no hairlines — a 1px rule scales to a quarter
|
|
of a pixel and simply disappears.

The grain is on the site to keep these low-alpha washes from banding, and on
|
|
the site it earns that. In a still it does not: scanning background rows of
|
|
both renders, the grainless card's gradients are already dithered by the
|
|
compositor (longest run of one green value: 1-7px over 420px, i.e. no bands

to break). Measured against the grained render it moves no channel by more

|
than 5/255 (mean 1.5) — and it costs 364KB, because per-pixel noise is

precisely what PNG cannot compress. An invisible layer is not worth doubling

a file every feed in the world re-fetches. Re-measure before restoring it. */
