/* Phan Home Money - styles (builder: shell). Contract: MONEY-CONTRACT.md v1.

   =====================================================================================
   SHARED CLASSES - money-spend.js and money-grow.js use EXACTLY these names (do not invent
   look-alikes; ask shell for a new one). Everything else in this file (.mt-*, .mc-*, .ms-*)
   is shell-private.
   -------------------------------------------------------------------------------------
   AREAS (r349: each area its own tint + 2px darker border; neighbours never share a hue)
     .m-card                 a section card (padding, radius, 2px border). ALWAYS add one tint:
     .m-card--blue  .m-card--gold  .m-card--green  .m-card--purple
     .m-card--rose  .m-card--teal  .m-card--slate  .m-card--orange
                             pick so two cards next to each other never share a tint.
     .m-card-head            flex row at the top of a card: <h2> on the left, buttons right.
     .m-card-sub             small muted line under the head.
     .m-banner               full-width notice inside a card (white, 2px border).
     .m-banner--red          red alert banner (interest you pay, charge after cancel).
     .m-banner--green        good-news banner.
   TILES / ROWS (items inside a card: white, 1.5px border, 6px colour bar left, alternate tint)
     .m-list                 vertical stack of .m-tile (gap 8px). Alternating faint tint is
                             automatic for .m-tile children of .m-list.
     .m-tile                 one record. Default bar = slate. Bar colour modifiers:
     .m-tile--blue .m-tile--gold .m-tile--green .m-tile--purple .m-tile--rose
     .m-tile--teal .m-tile--red .m-tile--orange .m-tile--slate
                             or set style.setProperty('--bar', '#hex') for a custom bar.
     .m-tile-main            flex:1 text column inside a tile.  .m-tile-title  bold name line.
     .m-tile-meta            small muted line (dates via ctx.fmtDate).
     .m-tile-side            right column (amount + Edit button).
     .m-row                  label left / value right line (flex, space-between, wraps).
     .m-grid2                two-column grid (one column under 360px).
   BUTTONS (all >= 44px tap targets)
     .m-btn                  plain white button, 1.5px border.
     .m-btn--primary         filled accent (main action, e.g. Save).
     .m-btn--danger          red outline (Remove). .m-btn--small = 44px tall compact padding
     .m-btn--add             round "+" button for card heads (aria-label required).
     .m-btn--block           full width.
     .m-actions              row of buttons with gap (wraps).
   CHIPS / SEGMENTS
     .m-chip                 small pill (button or span). .m-chip--on = selected.
     .m-chip--green .m-chip--red .m-chip--gold .m-chip--blue   status chips (text + tint).
     .m-seg                  segmented switch container (Week | Month | ...); children are
                             <button class="m-chip"> with aria-pressed="true" on the chosen one.
   NUMBERS
     .m-in                   money in: green #0f6b3a. ALWAYS also write "+" (never colour alone).
     .m-out                  money out: red #b42318. ALWAYS also write "−" / "-".
     .m-big                  big number (card headline figure).
     .m-muted                muted small text (4.5:1 on white and on every tint).
   PROGRESS
     .m-bar                  progress track; put ONE <span> inside and set span.style.width.
     .m-bar--over            red fill (over budget).   .m-bar--good  green fill.
   EMPTY / LOADING
     .m-empty                friendly empty-state box (dashed border, centred).
   FORMS (ctx.field / ctx.select / ctx.moneyInput / ctx.dateInput already use these)
     .m-field  .m-field-label  .m-field-hint  .m-input   (inputs, selects, textareas)
     .m-err                  red error line inside a sheet.
