/* ==========================================================================
   Seefa ERP Assistant — visual system

   Built on Apple's interface principles: translucent material for chrome,
   springs for anything the user can touch, feedback on pointer-down, and
   size-specific typography. Reduced-motion / transparency / contrast are
   first-class, not afterthoughts.
   ========================================================================== */

/* ---------------------------------------------------------------------------
   PALETTE — "Apple Modern"

     #F5F5F7  mist      page background      (light)
     #1D1D1F  graphite  primary text         (light) / page background (dark)
     #AAAAAA  silver    tertiary text, fills
     #007AFF  azure     the single accent

   Four colours only. Everything else is one of these at an opacity, which is
   what keeps it feeling like one system rather than a collection of screens.
   Semantic colours (success/warning/danger) are kept but used sparingly —
   restraint is the point.

   THEME SWITCHING
     :root                        light by default
     @media (prefers-color-scheme: dark) + :root:not([data-theme="light"])
                                  follow the OS unless the user overrode it
     :root[data-theme="dark"]     explicit user choice, wins over the OS
   The guard on the media query is what lets a manual "light" choice survive
   on a machine set to dark.

   the numbers come from the database, the plays come from the analysts'
   playbook. The label says which, so nobody mistakes a suggestion for a
   measurement. Styled on --success rather than --accent so it does not
   compete with the forecast box when both appear.

/* ==========================================================================
   PREMIUM GLASS THEME
   Frosted-glass surfaces over a strong, matte colour field.

     ink       #070B16 / #E8EBF4   the page (dark / light)
     cobalt    #5872FF / #3550E8   the accent: actions, the user's own words
     tangerine #FF8A3D             the second accent: brand details, sparingly
     violet, teal                  only in the background mesh

   The mesh is fixed to the viewport so the glass always has colour to blur.
   A fine grain over everything makes the colour matte rather than glossy.
   Real blur (backdrop-filter) is used only on chrome that floats over
   content (bar, composer, sheets, menus, sidebar, sign-in card); bubbles and
   cards are translucent over an already-soft background, which reads as
   frosted at no GPU cost.
   Placed last so it layers over the base system without rewriting it.
