/* Landscape print override for the shift page (app.js).
   Toggled on/off via link.disabled (CSSOM property, CSP-safe) by the
   週(横)/週(縦) print buttons. External stylesheet so it complies with the
   strict CSP (style-src 'self'; inline <style>/insertRule are blocked).
   Default (this disabled) = portrait. */
