/*
 * The site, wearing the theme the package ships.
 *
 * Every value here is lifted from source, not matched by eye. `ThemeDefinition.Default` is what a
 * form gets when nobody supplies a theme, and it is deliberately the loud option:
 *
 *     Preset = Neubrutalist          BorderWidth = 2      HeavyText = true
 *     Mode = Light                   ShadowOffset = 4     UppercaseHeaders = true
 *     Shape = Square (radius 0)      FontSize = 13        HeaderTracking = 0.05
 *
 * The palettes are `ThemePalette.Neo` and `ThemePalette.NeoDark` in
 * src/Interlude/Theming/ThemeDefinition.cs, colour for colour. Light and dark here are those two,
 * which is why dark is the light one *inverted* rather than dimmed — black outlines and black
 * shadows disappear on a dark backdrop, so both become bone white and the accent moves from hot
 * pink to a lime that survives being surrounded by it.
 *
 * The hard shadow is `WpfThemeApplier.HardShadow`: a DropShadowEffect with BlurRadius 0 at
 * direction 315, which is 4px down and 4px right of solid colour. Pressing a control removes the
 * shadow and translates the surface by the same 4px, so it drops onto where the shadow was. That
 * is reproduced on anything clickable.
 *
 * The one place this deliberately stops short of the product: prose. The node reference is 114
 * pages of dense text, and setting body copy in spaced capitals because the forms set their
 * *section headers* that way would be reading the rule and missing the point. Chrome, headings,
 * blocks and controls are styled hard; paragraphs are left alone.
