/* verify.css — the public HashMark check.

   This is an EVIDENCE page, not a marketing page and not a developer tool. So:
   calm, typographic, one column, generous measure, and no decoration that competes
   with the verdict. A reader arrives from a link, reads four answers, and leaves.

   THREE RULES THIS FILE IS ACCOUNTABLE FOR:

   1. COLOUR IS NEVER THE ONLY SIGNAL. Every verdict prints its status in words as
      well, so a screenshot, a printout, or a reader who cannot separate greens from
      reds loses nothing. The palette is Okabe-Ito, already colourblind-safe.
   2. THE NEUTRAL STATE IS THE DEFAULT. `.verdict` starts grey; the error colour is
      opt-in via `.verdict-bad`. `verdict-unchecked` is the ordinary outcome in a
      browser (no secp256k1 here, ever), and an honest signer must never be painted
      red because of a library missing from the reader's machine.
   3. NO HORIZONTAL SCROLL AT PHONE WIDTH. Everything wraps. The only values long
      enough to threaten that are 64-character hex identifiers, and `.mono` breaks
      them anywhere rather than pushing the page wider.

   The two VERDICT colours are the inspect tool's exact values (--color-ft #0072b2
   and --color-p2pkh #595959), so a verdict a reader checks on one page against the
   other looks the same on both. The rest of the palette is this page's own and is
   deliberately not a copy: /inspect/ is a dense field-oriented diagnostic, and
   importing its stylesheet would drag a hundred rules this page has no elements
   for. */
