{#- ═══════════════════════════════════════════════════════
    Shared fragments, in the service's own vocabulary.

    Every one of these obeys the two disciplines that get broken
    by reflex: nothing is enclosed in a border or a box, and every
    bar is drawn at the one shared width so any two percentages in
    the service compare directly.
    ═══════════════════════════════════════════════════════ -#}

{#- A degraded service. Teletext's failure was a page that did not
    arrive, said in red where the content should have been — not a
    panel with an icon and a left border. -#}

{#- THE ONE RULER. Every bar in the service is drawn here and
    nowhere else, at --bar-cells wide, filled in whole cells. Pass a
    percentage; the macro rounds it to cells so a bar never ends
    mid-character. `tone` picks the colour by threshold. -#}

{#- Disk temperature / spin state. A spun-down disk reports no usable

{#- A disk/cache row for the phone reflow of the System table (below
    560px, where a six-column table stops fitting and its horizontal
    scroll would hide the bar and the temperature — the two readings
    that matter most). Name, the one shared bar, and the temperature
    sit on one line; device/size/free sit beneath as a sub-line. The
    desktop <table> stays the table at wider widths; this is not a
