/* Archeion+ — main.css: βάση και components (οι τιμές έρχονται από το tokens.css)

   1. Το «+» του λογοτύπου είναι σύστημα: φτιαγμένο από φύλλα χαρτιού στα εξώφυλλα,
      σημάδι καταχώρισης στις γωνίες των πλαισίων, κουκκίδα σε λίστες και συνδέσμους.
   2. Κυρίαρχο χρώμα το μαύρο του λογοτύπου. Λευκό και ανοιχτό γκρι για ανάγνωση,
      ένα μόνο χρώμα έμφασης (πετρόλ) για γραμμές, αριθμούς και κουμπιά.
   3. Τυπογραφία: τίτλοι Source Serif 4, κείμενο και πίνακες Inter με ισοπαχή ψηφία. */
