/*
 * Sharper light-on-dark text.
 *
 * The nav renders #dce6ef at weight 500 on #16283a. Browsers use subpixel
 * antialiasing by default, which adds colour fringing to glyph edges. On a dark
 * background that fringing reads as bloom, and the text looks soft even though
 * nothing is actually blurred.
 *
 * Switching those surfaces to grayscale antialiasing removes the fringing.
 * Applied only to the dark chrome, because on the light content areas subpixel
 * rendering is genuinely sharper and should be left alone.
