/* WS-062 — user display settings: theme, text scale, typeface.
 *
 * The owner has presbyopia. A single fixed size cannot serve him and
 * every other pilot at once: the §4 floor was 18px, he ran the interface
 * at that size, found labels breaking words and pushing panels past the
 * right edge, and lowered his own rule to 16px on 2026-08-05. That was a
 * trade forced by having one number. This layer removes the need for one
 * number - each user picks, and the choice follows him everywhere.
 *
 * The selected value is a real effective text size, not document zoom.
 * Zooming the whole root to reach 32px also halves the effective layout
 * viewport, which made controls disappear and created page-wide horizontal
 * overflow. The late sim-pit typography layer already routes text (including
 * SVG text) through canonical variables, so this file changes those values
 * while leaving the physical viewport and 44px targets intact.
 *
 * Additive by design: this file defines its own tokens and never edits an
 * existing stylesheet, so it cannot collide with the readability work in
 * flight on another branch.
