/**
 * THE copy control — a verb about a VALUE, so it rides the value it copies
 * rather than a trailing column (see `docs/composition.md` § A VERB GOES WHERE
 * ITS EFFECT LANDS: a reserved column is paid by every row for the benefit of
 * one, and a row carrying two values gives that column nothing to name).
 *
 * It owns the whole gesture: the clipboard write, and what came of it — the
 * glyph flips to a check and the tooltip to the pack's "Copied" for ~2s. The
 * confirmation follows a REAL write; an unreachable clipboard — a non-secure
 * origin, a denied permission — flips the glyph to the alert mark and says so in
 * the pack's words instead, rather than claiming a copy the user cannot paste or
 * leaving the browser to log a rejection nobody reads.
 *
 * The FAILED state is the one that also changes the announced name. A name that
 * moves under a screen-reader user normally reads as a different control, which
 * is why the confirmation leaves it put — but the check is a channel only the
 * eye has, and nothing else would tell a reader who cannot see the glyph that
 * there is nothing on their clipboard.
 *
 * **Render it unconditionally and let it disable itself.** An empty `value`
 * disables the button, which is the same rule an `Inline*` editor's `actions`
 * slot follows: a control that appears once a value is non-empty changes the
 * cell's width as the value arrives, and a register whose columns shift as rows
 * load is worse than a dimmed glyph.
 *
 * Nested inside a `PressableRow`/`TableRow` it claims its own press — the row
 * does not also open.
