/* Meal Repository — the whole stylesheet.
 *
 * One hand-written file, no build step and no framework (plan §5). It is served static and cached,
 * which is the only reason it is not inline in base.html any more.
 *
 * The look is meant for the way this tool is actually used: one or two people, most of a working
 * day, reading carefully. So it is calm rather than striking, dense rather than airy, and colour is
 * spent only where it carries meaning — allergens, review state, and whether the gate said yes.
 * Every colour below is a token, which is what makes the dark palette a swap rather than a rewrite.
