/* =============================================================================
   STD Booking — assets/styles.css
   Original, hand-authored design system for stdbooking.com. Framework-free,
   mobile-first, self-contained: no imports, no fetches, no preprocessor.

   DESIGN LANGUAGE
   ---------------
   Calm, discreet, medically credible, privacy-respectful. Deep indigo-violet
   ink on a cool porcelain page, soft white surfaces, one confident primary,
   and a restrained rose accent reserved for action, emphasis, and focus.
   Generous whitespace, soft layered shadows, gentle corner radii, and an
   editorial serif display face paired with a humanist sans for body text.

   Display face: Newsreader (serif). Body face: Instrument Sans.
   Both families are requested in a single Google Fonts link held in the
   FONT_LINK constant at the top of src/templates.js.

   PALETTE
   -------
   Ink            #1B1830   primary text
   Ink soft       #4C4964   secondary text
   Primary        #4A3FA8   deep indigo-violet, the single confident brand color
   Primary 700    #3A3190   link and text use on light surfaces
   Primary 800    #2C2568   strong text, solid hover, dark surfaces
   Primary 950    #161231   footer background
   Accent         #C05580   soft rose, rules and focus ring
   Accent 600     #A83E68   accent text on light surfaces
   Amber 300      #E9B87A   warm labels on dark surfaces
   Amber 100      #FBF1DE   price chip tint
   Bone           #F5F4FA   page background
   Paper          #FFFFFF   card and panel background
   Line           #E3E1EF   hairlines
   Every text pairing defined here meets WCAG AA contrast (4.5:1) or better
   against the background it is used on.

   TOKEN CONTRACT
   --------------
   Legacy token names remain defined because the markup and existing rules
   reference them: --ink, --ink-soft, --pine, --pine-700, --pine-100, --coral,
   --coral-600, --amber, --bone, --paper, --line, --line-strong, --radius,
   --radius-sm, --maxw, --maxw-prose, --font-head, --font-body, --space-1
   through --space-9, --fs-xs through --fs-hero, --lh-tight, --lh-heading,
   --lh-body, --ease, --dur.
   The header brand mark is the generated PNG logo at /assets/logo-mark.png
   (indigo plate, rose flask). The legacy --pine and --coral aliases below
   remain defined for backward compatibility with older markup and rules.
