/* Prepwise - Main Stylesheet
 *
 * Theme: "Kitchen Garden" - grassy greens over a wooden-sepia ground.
 *
 * Everything visual is driven by the token ramps in :root below. The utility
 * class names still read gray/blue/green/etc. because they are used in
 * index.html and in the template strings in app.js, but they are slots rather
 * than literal colors: `blue` is the oak/walnut accent, `gray` is warm sepia
 * stone, `yellow` is honey, `orange` terracotta, `red` brick, `purple` plum.
 * Retheming the app means editing the ramps, not the markup.
 *
 * A dark ("evening walnut") palette swaps the same tokens under
 * :root[data-theme="dark"]. The attribute is set by display.js before first
 * paint; Settings offers Light / Dark / Follow system, and "system" is resolved
 * there rather than in a media query here - see the note above that block.

     * Cards are cherry-sepia, not white. A white card on a wooden ground is the
     * brightest thing on the screen by a wide margin, and this is an app you
     * read from across a kitchen for twenty minutes at a stretch.
     *
     * The whole light "paper" range is pitched off one measured reference: the
     * Shopping List panel (--t-50), which read comfortably at 0.848 luminance
     * sitting directly on the board. The card matches it at 0.847, and every
     * --x-50 tint sits just below so a callout still reads as a callout. A first
     * pass at ~0.90 was too timid to see; a second, done by scaling brightness
     * alone, hit the number but came out grey, because chromaticity survives
     * scaling and the warmth has to be dialled in separately. Hence the hand-set
     * values here: lightness AND warmth both matter.
     *
     * Legibility is unaffected - body ink clears 7.7:1, well past AA - and
     * `theme.spec.js` holds the surface above 0.8 so "warm" cannot drift into
     * "dim", and holds every tint at or below it so glare cannot creep back.
     *
     * --field stays a step brighter than the card it sits on, so an input still
     * reads as somewhere to write rather than as more card.

/* ---------------------------------------------------------------------------
 * Color utilities
 *
 * The class names are inherited from the original Tailwind-ish scale and are
 * kept as *slots*, not literal hues - every value comes from a token ramp in
 * :root, so the whole app re-themes from one block. The mapping is:
 *
 *   gray     -> --n-*  Sepia stone - neutrals, text, quiet fills
 *   green    -> --g-*  Garden green - the brand hue: primary, fresh, available
 *   blue     -> --w-*  Oak/walnut - the wooden accent (this app has no blue)
 *   yellow   -> --h-*  Honey - caution, expiring soon
 *   amber    -> --a-*  Toasted amber - advisory notices
 *   orange   -> --t-*  Terracotta - restock, expires today
 *   red      -> --r-*  Brick - expired, destructive
 *   purple   -> --p-*  Plum - conflicts, AI share
 *
 * Two ramps per family: --x-N paints surfaces/borders, --x-t-N paints text.
 * They are the same value in light mode and diverge in dark, where text has
 * to lighten while button fills must stay dark enough to carry white labels.
