/*
 * ID Photo JP — the product site of an offline Japanese ID photo (証明写真) app.
 *
 * 0.2 — the page reads as a technical sheet: millimetre rulers along the top and
 * left edge of the hero and page heads, a faint mm grid, dimension lines, and
 * every ID photo drawn to one scale. One accent (the app's blue, or the site's
 * primaryColor setting). A photo is paper: drawn photos and print sheets stay
 * white in dark mode too, because a printed photo does not change with a screen.
 *
 * Inter is self-hosted (assets/fonts) — still no request to anybody else's
 * server. Japanese glyphs fall back to the platform's own Japanese faces.
