/* yomikei.com: one stylesheet for all pages (the homepage design "D": manga ink and panels, with room). */
/* Design D, "Ink and panels, with room": A's manga vocabulary (caption boxes, screentone, a yonkoma for the plan, a
   panel of focus lines to close) laid out with B's space. Only things that are panels get a border: the hotkey and
   the four steps of the plan. Everything else sits on open paper.
   Colours (2026-10-19, Argon's palette): warm paper and soft ink instead of pure white and black; quiet 1px lines
   (--line) rather than ink borders; things you touch (keycaps, the email box, the theme switch) on a slightly raised
   surface (--surface); the manga page unframed with a soft shadow. Light "Tankōbon", dark "Sumi ink". */
