     This block used to read `#ffffff` — "white paper, held by a firm hairline" —
     on the theory that a field should RISE on paper while it sinks in the dark.
     In practice a wall of pure white boxes on a warm cream page is glare, and it
     was the first thing reported about the light theme twice over.
     The look being asked for is the Memories ledger's own search box, which sits
     one step DOWN from the page it rests on. So light mode now agrees with dark
     mode about direction — a field is always a well — and only the depth differs.
     Chosen to stay a visible step below --panel (#f3eee4), the deepest surface a
     field normally sits on, so a field reads as a field on the page, on a panel,
     and inside a dialog (which is --surface). */

     floor against --panel demands. The first cut of this file darkened by feel and
     landed at 4.6–6.7:1 — every dot read as near-black and the six were no longer
