// =====================================================================
// LABELS
// General notes:
// - `text-halo-rasterizer: fast;` gives a noticeable performance
// boost to render times and is recommended for *all* halos.
// ---------------------------------------------------------------------
// Languages
// There are 5 language options in the MapBox Streets vector tiles:
// - Local/default: '[name]'
// - English: '[name_en]'
// - French: '[name_fr]'
// - Spanish: '[name_es]'
// - German: '[name_de]'
@name: '[name_en]';
// ---------------------------------------------------------------------
// Fonts
// All fontsets should have a good fallback that covers as many glyphs
// as possible. 'Arial Unicode MS Regular' and 'Arial Unicode MS Bold'
//are recommended as final fallbacks if you have them available.
//They support all the characters used in the MapBox Streets vector tiles.
@fallback: 'Super Grotesk Offc Pro Regular';
@sans: 'Super Grotesk Offc Pro Regular', @fallback;
@sans_md: 'Super Grotesk Offc Pro Medium', @fallback;
@sans_bd: 'Super Grotesk Offc Pro Bold', @fallback;
@sans_it: 'Open Sans Italic', @fallback;

// The country labels in MapBox Streets vector tiles are placed by hand,
// optimizing the arrangement to fit as many as possible in densely-
// labeled areas.
