/*
 * Typing Treasure Quest — visual theme.
 *
 * Palette choices are deliberately NOT plain red/green: "incorrect" uses a
 * warm amber (never red) per the brief's "no red-screen effect" rule, and
 * every color pairing below has been checked against WCAG AA's 4.5:1 text
 * contrast minimum (3:1 for large text/UI outlines) rather than picked by
 * eye, the same discipline com_lander's own CSS documents inline.
 *
 * No external images: only CSS/inline-SVG-drawn shapes, per the brief's
 * "avoid external dependencies" rule. The one exception is the typeface:
 * Atkinson Hyperlegible (SIL Open Font License, self-hosted below rather
 * than pulled from a CDN at runtime -- see media/assets/fonts) was
 * designed by the Braille Institute specifically to disambiguate
 * easily-confused character pairs (capital I vs lowercase l vs digit 1,
 * 0 vs O) without reading as clinical -- it's used in general-audience
 * reading apps, not just accessibility tools, which is why it still pairs
 * fine with this game's playful color/shape language.
