/* Petromix · Log critical fluid sample (field PWA screen)
   Scoped under .fs. Built for rugged phones in bright light: high contrast, 48 px+ targets, one-hand use.
   Design tokens live on .fs — see README "Design system".

   IN THE APP: the supplied sample-log.css, with these changes.
     1. No Google Fonts @import. Barlow, Barlow Condensed and IBM Plex Mono are
        self-hosted; their @font-face rules are in advisor.css, which the rep
        app already loads, so nothing is fetched and the screen works offline.
     2. The screen opens as a full-screen sheet over the app (.fs-sheet), up to
        560 px wide on a desktop, with the page behind it held still.
     3. Logical properties (inset-inline, padding-inline, text-align: start…),
        so the layout mirrors in Arabic; the back arrow flips.
     4. Colours used as TEXT have their own tokens (--fs-brand-text,
        --fs-ok-text, --fs-amber-text, --fs-crit-text). The fills stay the
        design's, so a yellow button is still yellow while yellow text on a
        light background is darkened enough to read.
     5. A light theme, keyed off the app's :root[data-scheme="light"]. The
        dark values are the design's.
     6. Measured: every text colour in both themes is at least 4.5:1 on its
        background (the design's placeholder grey #6E7C89 is 4.53:1 on the
        input well, so it stays).
     7. Additions for the app's fields: smaller sample-point quick picks
        (.fs-tag--sm), the live camera inside the scanner (.fs-cam), and
        "Take a photo of the tag" when there is no camera (.fs-scan-photo). */
