/* Faith Companion — site styles.
 *
 * The type and the palette structure follow knsprojects.online: IBM Plex Sans
 * over a cool near-white, hairline borders, small radii, a mono face reserved
 * for eyebrows and labels. What is NOT borrowed is that site's status-dashboard
 * motif — terminal panels and OK dots are right for an infrastructure practice
 * and wrong for a book you read at five in the morning.
 *
 * The brand colours are the APP'S OWN, not the reference site's. `--brand`
 * #1B5F8E and #4FA8E8 are `FcTokens` out of lib/fc_tokens.dart, so a reader who
 * arrives from the App Store meets the same blue twice. They happen to sit a
 * few degrees from knsprojects' #0f4c8a, which is why the two sites read as
 * siblings without either one borrowing the other's identity.
 *
 * EVERYTHING IS SELF-HOSTED. The vhost's Content-Security-Policy is
 * `default-src 'none'` and its comment says the site is "entirely
 * self-contained — no scripts, no CDN, no font host, no analytics". Adding
 * Google Fonts would have meant punching two holes in that for a typeface, so
 * the six woff2 files sit in assets/fonts and the policy gains only `font-src
 * 'self'`.
 */

/* --- fonts ---------------------------------------------------------------
 * Latin subset only. `font-display: swap` so text paints immediately in the
 * fallback and reflows — on a Zimbabwean mobile connection, a blocking font is
 * a blank page.
