   The floor is the tile's own content, not a fixed 64px. The previous

   `.metric-val` was `white-space: nowrap`, so a long value overflowed its own
   card box. Because each `.metric-card` paints an opaque background in DOM
   order, the next tile then painted OVER the previous tile's overflow --
   which reads as "clipped mid-string" with no ellipsis and no `overflow`
   rule anywhere to explain it. Measured 2026-09-08 on Jeff's Chrome
   (1536x695 CSS px, DPR 1.25, prod Blue, centered Winemaking workspace):
   a 10-analyte lab card got ~72px per tile and every value but the last was
   painted over.

   `min(9rem, 100%)` keeps the floor from itself overflowing a pane narrower
   than the floor -- the copilot rail is user-resizable down past 300px, and
   NO breakpoint in this file can see that, because every media query here
   keys off VIEWPORT width while the pane's width is set by a drag handle.

/* ───────────────────────────────────────────────────────────────────────────
   tank-temp-chart — the live SCADA temperature curve inside a chat reply.

   ⛔⛔ COLOURS COME FROM THE --tbm-* TOKENS, NEVER FROM --bs-*. This app ships
   Bootstrap 5.1.0, and --bs-secondary-color / --bs-border-color / --bs-tertiary-bg
   are Bootstrap 5.3 color-mode variables that DO NOT EXIST here. tokens.css defines
   them, but only inside [data-theme="dark"] — so a rule written against them renders
   correctly in dark mode and silently drops in light mode: an undefined var makes the
   declaration invalid at computed-value time, so `stroke` becomes none and the shape
   is DRAWN AND INVISIBLE. Measured on prod 2026-09-04 at 1506x698 CSS / dpr 1.25,
   light mode: the setpoint line, every gridline, the frozen-run dash, the now-rule and
   the card border were all missing, and no test could see it — the elements are in the
   DOM with correct geometry. The --tbm-* set is defined for BOTH themes at :root, and
   is what TankTempGraph.razor.css (the TankBoard drawer) already uses, so pointing here
   is also what makes the two charts read as the same chart.

   ⛔ The hover tooltip is revealed by CSS sibling styling alone. There is no
   @onmousemove on the SVG — on the Blazor Server hosts that would round-trip
   the circuit per mouse move.
