/* Ported from the original Apps Script app's Styles.html (2026-09-02 refresh) - JCC logo,
   login-page wallpaper photo, toast notifications, mobile off-canvas drawer. The two images
   below were embedded as base64 in the original; extracted here to real files
   (public/images/logo.png, public/images/wallpaper.jpg) instead - same look, much smaller
   page weight and normal browser caching.

   2026-09-15 redesign - "Rebar Tag": a neutral galvanized-steel UI (one steel-grey accent
   doing almost everything, instead of a saturated brand blue) plus a small set of
   colour-coded dots used only where the colour is already real information - your own bar
   marks are literally named after their tie-wire colour ("STARTING REBAR X' - MAGENTA",
   "ALONG Y' AXIS - RED/GREEN/BLUE"), so the Mark column across the app now shows a matching
   dot next to any mark whose name says so (markDotHtml() in app.js) instead of inventing a
   decorative colour system. One typeface throughout (IBM Plex Sans) carries hierarchy by
   weight, not by mixing faces. Every existing class name is kept as-is - only values (and a
   few component treatments that genuinely need to flip, like the sidenav going light) - so
   none of the markup already built in app.js/print.js needed to change for this. */
