/* THE LAMP : two registers, one switch (KA, 2026-10-05, Mikha'el's ruling).
   The house keepeth two registers of light, and the reader chooseth:
     - the DARK register: the deep-navy house signature (the default), and
     - the BRIGHT register: the scripture-white reading light.
   On a house-dark room the pill readeth "Raise the lamp" and showeth the
   bright register; on a doctrine-white room * the pill readeth "Dim the
   lamp" and bringeth the house dark. The reader's choice is remembered in
   their own browser, in one key, never sent, never counted.

   THE LAWS:
     1. Never flash the wrong register. The register is applied by an
        ordinary same-origin script in each page's head (js/lamp-early.js),
        BEFORE the first paint: a stored choice, or the system's dark wish,
        setteth the class pre-paint.
     2. Honour prefers-color-scheme: a reader whose system asketh for dark,
        and who hath made no choice of their own, getteth the dark register
        unasked. Their own choice, once made, alway winneth (legacy stored
        'day' -> bright; legacy 'dim' -> dark).
     3. Honour prefers-reduced-motion: the change is a settling of colour,
        never a fade. No motion is added anywhere by this mode.

   The mode is carried by the house's own tokens, so every room that ever
   used --paper or --ink followeth the register, and a room added tomorrow
   is reached as well without a line of work. Nothing is hidden and no word
   is changed: the light, only.

   THE BOUNDED OVERRIDES (the keeper's word: "bounded bright-register
   overrides for literal-colored rooms"): the rooms whose sheets painted
   literal colours rather than the house's tokens are carried to the bright
   register by name below — the breach family, the not-found room — and the
   two canvases that are their own doctrine (the Cell; the Question's hate
   prelude) are kept dark in both registers. Every override is scoped to
   the register and to the named room; nothing else is touched.

   * The doctrine-white rooms (the sixteen ministries, the Magnificat, and
   the House of the Name) keep their white paper by the keeper's ruling of
   2026-10-04; the lamp bringeth them the house dark at the reader's word.
