Derive Monitor's column count from what the cards actually need, so no width forces a sideways scroll

+   The grid lives here rather than in a style="" on the div, which is why nothing below needs
+   !important any more. An inline style outranks every stylesheet rule, so the old overrides had
+   to shout to be heard; moving the declaration into the cascade lets the ladder simply cascade.
+
+   BREAKPOINTS ARE DERIVED, NOT CHOSEN. A column count is viable exactly when the cards still fit:
+
+       window >= N * card-floor + (N-1) * gap + wrap-padding
+              =  N * 200       + (N-1) * 12  + 20
+
+   which gives 12:2552  10:2128  8:1704  6:1280  4:856  2:432  1:220. Every value below is that
+   arithmetic minus one, never a number picked by eye. If .vv-card's 200px min-width ever changes,
+   these must be recomputed — they are a function of it, not independent settings.
+
+   This replaces a single 8 -> 4 step at 1024px, which left a 679px dead zone (1025-1704) where
+   eight columns were forced into a box that could not hold them. A 1327px tablet in portrait
+   overflowed by 377px — the "scroll sideways to see the last fifth" bug.
+
+   minmax(0, 1fr), not 1fr: bare 1fr means minmax(auto, 1fr), and that auto floor resolves to the
+   larger of min-content and min-width. One card holding an unbreakable string would otherwise
+   push its column past its share and drag the whole grid out of the container. The row axis has
+   carried this guard for a long time (grid-auto-rows: minmax(0, ...)); the column axis never did. */
