/* SINTEF Energy Virtual Lab (vLab) - felles stil for hub, landingsside og stats.
 *
 * Profil: SINTEF-blå #003c65 bærer, siden skal oppleves som blå og hvit.
 * Typografi er Calibri (Carlito som åpen erstatning), ingen fonter lastes
 * fra tredjepart. Ingen versaler, ingen emojier.
 *
 * vLabs eget motiv er notebook-cellen: en tynn ramme med en kraftig
 * venstrestolpe (cellestolpen) og en monospace-markør [n] i margen, som i
 * Jupyter. Stolpen er cyan (#64cbe6, nikk til sintef.energy) når noe er
 * valgt eller aktivt, og mellomgrønn (#14b978) når noe er kjørt/ferdig/OK.
 * Bakgrunnen i heroen er et svakt rutenett, som millimeterpapir i et lab.
 * Grønt og cyan brukes bare på flater, streker og markører - aldri som
 * brødtekst på hvitt (for lav kontrast).
 *
 * Mørk modus er definert to ganger (auto og manuell). Blokkene skal være like.
 * Sider legger egne regler i egne filer (landing.css, spawn.css ...) og
 * bruker bare tokenene herfra - aldri hardkodede farger.
