FabledSwordLightTokens, flat tokens (accent / moss / etc.) are shared

theme.

Widgets read tokens via Theme.of(ctx).extension<FabledSwordTheme>().
Material 3 ColorScheme bound to FabledSword tokens. Body text uses
GoogleFonts.interTextTheme() so the fonts work without bundling .ttf
files (offline-from-cold-launch is a separate question once #357 lands).
