/*
 * Slidemill dashboard. Style: "True-black flat" (tasteskill app sheet, seed 919533666).
 * Elevation by lightness alone (#000 ground, #111 card, #2a2a2a nested), no borders or shadows on
 * cards at rest, the active nav item is its label brightening, the primary action is a white pill.
 * Colour lives on data only: TikTok's cyan is the one data hue (scores, the swipe-through strip,
 * the schedule). It never fills a button, a tab or the nav.
 *
 * Type: the product's own face. Slides are set in Montserrat (TikTok's classic caption face), so the
 * interface is too, one family at 400-600 with tabular figures (static/montserrat-ui.woff2, OFL).
 *
 * Grid: canvas = viewport - 210px sidebar; 29px gutters; one 14px gap everywhere.
 * Overview at 1440: 1440 - 210 - 2x29 = 1172 = main (774) + 14 + rail (384).
