/* 93 - Battalion Attendance App. Mobile-first, canopy as the design template
   (see D:\claude_orion\canopy for the reference: css/style-01.css tokens,
   bottom nav pattern, card/form/modal idioms). Ported look and interaction
   idioms, not canopy's code wholesale: 93 is a single small stylesheet (no
   need for canopy's 11-file split), system font stack instead of bundling
   Fira Sans (those font files live only in canopy's own repo), and a status
   pill system canopy has no equivalent of (93's 7 attendance statuses). */
