	/* An unbreakable value must not leave the card, in ANY .table. Asking what KIND of table it is
	 * first leaves a third-party key/value `<div class="table">` matching nothing, so one unbroken
	 * token — an ICCID, a base64 key, a DUID — holds the column open and pushes the table outside
	 * its card (measured on 3ginfo-lite).
	 *
	 * Not scoped to the phone tier: that leaves a hole where the column is narrow but the WINDOW is
	 * not (with a 130-character token the table escaped its card by 147px at 900px and 279px at
	 * 768px), which is the argument the fit engine is built on — whether something fits is a
	 * property of the content and its column, not of the viewport. The cost is nil: across 8 pages
	 * x 4 widths x 849 text cells nothing else changes.
	 *
	 * `anywhere`, not `break-word`: `break-word` permits the break without reducing the cell's
	 * min-content contribution, so a `display: table` box still cannot shrink below its widest
	 * token and the column stays open — tried, and the table stayed 355px wide in a 346px column.
	 *
	 * That is a CONTAINMENT default, right for every tier with nowhere to put an overflow — a
	 * key/value include, the config table, the Overview meter rows. It is wrong for the one tier
	 * that IS measured: a data table can card, break one column or scroll, so it wants the truth
	 * instead, and theme/30-tables.css gives it `break-word` for as long as it is a table. Do not
	 * unify the two by moving either.
	 *
	 * Set per ROLE: a value may break anywhere, a label breaks at words. `anywhere` costs a
	 * min-content of ONE CHARACTER, which is the point on a value — the column may collapse rather
	 * than push the table out — and the bug it looks like on a header, since an auto-layout table
	 * hands the surplus to whichever column asks loudest and the header row pays: measured on
	 * Processes, `PID` came out as "PI/D" and the header row stood 104px tall, against 54px with
	 * the floor at its longest word (issue #32).
	 *
	 * `break-word` for the label, not `normal`: a header that IS one long token must still break
	 * rather than overflow, it just may not shrink the column below that word. */

	/* …and the first column is a label too, whichever element it is made of.
	 *
	 * `anywhere` costs a min-content of one character, and auto table layout hands each column its
	 * share by MAX-content, so a two-column key/value table whose value is one enormous token
	 * starves the key column down to that character — measured at 8000 characters of value, the key
	 * column fell from 95px to 55px, and on the reporter's host the header read one glyph per line
	 * (issue #36, on Firefox and Blink alike).
	 *
	 * `break-word` puts the floor back at the longest WORD, the same trade `.th` makes above: the
	 * first column is the row's identity, and it is what you read the table by.
	 *
	 * A carded row is exempt and must be: `.table.fs-stacked .td` (theme/30-tables.css) restates

	/* The empty-table plate: three lines of leading plus the cell inset it sits in, so it keeps the

	 *
	 * Out of flow on purpose: a single-cell row in a `display: table` spans only the FIRST column,
	 * so in flow the plate is a narrow box under column one and its sentence becomes that column's
	 * max-content, widening it (275px -> 502px on an empty section). Absolute takes it
	 * out of the column sizing entirely and `inset-inline: 0` spans it across the table.

	 * printed straight across the totals: measured on luci-app-dockerman's Containers, Images and
	 * Volumes tables (issue #36) as a 1190x35 overlap, the full width of the table, identically on
	 * Blink and on Gecko 153. With no `bottom` at all an absolutely positioned box keeps its STATIC
