/* =====================================================================
   Swift calculator kit  (calc.css, v1)
   Loaded after /assets/css/main.css on every calculator page.
   Hallmark . component: calculator kit . genre: modern-minimal utility . theme: Swift (navy/teal tokens from main.css)
   states: default . hover . focus . active . disabled . loading . error . success
           (form controls, buttons, seg, switch, range, drop zone; links and disclosures: hover/focus/active)
   Forced-state classes for the kitchen-sink demo: .is-hover .is-focus .is-active
   State hooks: :disabled / [aria-disabled=true], [data-state=loading|error|success] (button, drop, field, switch,
   seg), [aria-invalid=true] (inputs), [aria-busy=true] (seg, switch).
   pre-emit critique: P4 H4 E4 S4 R5 V3 (Variety is low on purpose: a utility kit should look like the site around it)
   contrast: pass. Checked ratios (WCAG, on white / on --gray-50):
     --calc-muted #5a6778 5.76 / 5.37 . --calc-accent #17706e 5.87 / 5.47 (white text on it 5.87)
     --calc-field-line #8a95a5 3.03 (UI component border) . --calc-focus (--teal-dark) 3.90
     --calc-error #b42318 6.57 . --calc-warn-ink on warn-bg 6.95 . --calc-ok #1b7a4b 5.34
   Everything is scoped under .calc-page or a calc- prefixed class. main.css globals that leak in
   (section padding, h1-h4 sizes, p colour, ul reset, button reset) are neutralised below.
