/*
 * Spry CSS theme: "dwarf" — a GNOME libadwaita / Adwaita clone
 * ---------------------------------------------------------------------
 * Ported from the ARC Adwaita reference (libadwaita's own stylesheet):
 * flat 9px buttons with 17px side padding, bold labels and 7%/16%
 * currentColor hovers; opaque accent primaries that brighten 10% on
 * hover; filled borderless entries (#e6e6e7 / #38383c) with a 2px
 * accent focus edge; boxed-row cards (12px radius, shade hairline, no
 * shadow); a hairline-outlined progress trough; 46x26 switches; dim
 * caption column headers; GTK tab bars (the checked tab is a
 * view-surface card bridging the strip's hairline into the panel);
 * flat headerbar dialogs with a centred bold title; a link/accent
 * split (#0461be / #81d0ff text over the same #3584e4 accent_bg in
 * both modes). Shadows appear only on popovers and dialogs. Light +
 * dark: the Adwaita dark palette repeats verbatim in the forced-dark
 * and auto-dark blocks below.
