/* Astra One. A star atlas printed in lapis: engraved pale-blue line work, cyanotype photographs, one gold star.
   Type: Archivo for headings (wordmark at its widest), Instrument Sans for text, Martian Mono for labels and figures.
   Shape rule: everything rectangular is cut at 4px (buttons, chips, inputs, cells, plates, photos). Anything round is
   an instrument: the globe, the practice circles, the dial, the signal rings and the arrow buttons.
   Theme rhythm: lapis sections, with white paper below the hero, behind How we work and behind the FAQ.
   Frosted glass only on things that sit over moving content: the nav, the mobile menu, the open industry caption, the phone notification.
   Label rule: gold mono caps after a gold star, only on the three practice sections (Build, Grow, Reach), which map to the circles.
   Spacing rule: sections 128px desktop / 88px mobile, heading to content 48px, gutters 24px / 16px.
   Z-index scale: art 0, content 1, nav 50, menu 55. */
