/**
 * File: map-modes.css
 * Purpose: Relief/outdoor previews, trail legend, and cartographic-label toggle.
 * Placement: Loaded only by map.html after the shared styles.
 * Dependencies: Layer menu primitives defined in styles.css.
 * Public selectors: Preview swatches, .trail-legend, .layer-toggle and basemap attribution logo.
 * Side effects: Shows independent tool legends and reserves measured attribution space below controls.
