   Typeface : 'Plus Jakarta Sans' everywhere. 'IBM Plex Mono' for figures,
              labels and eyebrows. Never Inter. Never Space Grotesk.
   Colour   : navy / blue / paper. NO PURPLE ANYWHERE. NO EMOJI ANYWHERE.
   Rule     : every colour is declared for the FIRST time on bare :root.
              The two dark blocks at the bottom REDEFINE tokens only —
              they never introduce a colour, and no component rule below
              hard-codes a hex value.

   3b. LANDING DEVICES
   The marks that carry the MyHotelAnalytics voice inward from the splash
   page. Read this block before inventing anything.

   TWO COLOUR LAWS, applied throughout the file below:

     1. --muted NAMES DATA. --faint NAMES THE PAGE.
        A label attached to a figure, a panel name, a table header, a status
        word -> --muted. A caption, a timestamp, a footnote, a page-level
        eyebrow, a chart axis tick -> --faint. This is a deliberate one-step-
        darker deviation from the splash page, and it exists because a
        housekeeping supervisor reads this at 6am on a phone in a corridor.
        Do not "correct" it back.

     2. --bad IS A MARK, NEVER A GROUND.
        A 2px left rule, a 1px ring, an underline, an ink colour on a figure
        or a word. Never a filled badge, never a button, never a row
        background, never a nav highlight. The ONE permitted use of
        --bad-tint as a ground is the interior of .numeral-anno, because the
        splash page does precisely that.

   --bad in this app is byte-identical to the splash page's --anno. It IS the
   annotation ink. Nothing below declares a new custom property; every name
   used here already has a value on bare :root and in both dark blocks.
   ========================================================================== */

   8. PANELS
   The card DISSOLVES. A panel is a layout stack whose own head supplies its
   top edge as a hairline; the white-rounded-box-on-grey is the exact generic
   furniture this pass exists to remove.

   .card       -> no ground, no border, no radius, no shadow, no hover reveal
   .card-lined -> the GROUND variant. A panel hosting a CHART, or a table with
                  a sticky header or sticky first column, MUST keep this,
                  because .chart .lbl draws its halo with stroke:var(--paper)
                  and .table th / .va-sticky-col paint themselves var(--paper).
                  Lose the ground and every data label gets a white halo on a
                  grey field. Not negotiable.
