  IQ Platform - _app/assets/css/forms.css

  Platform: 0.1.1
  Version: 0.1.2
  Created: 2026-04-27
  Updated: 2026-04-27

  Description: Form controls. Inputs, textareas, selects, labels,
  fieldsets, error states, help text. Every IQ product builds forms;
  the platform owns the look so every product feels like the same
  family.

  Class vocabulary:
    .form-group     -- wraps a label + input pair
    .form-row       -- horizontal flex row of .form-group blocks
    .form-label     -- field label (uppercase display font, small)
    .form-input     -- text-like inputs (text, email, password, number, date)
    .form-select    -- select dropdowns (with custom chevron)
    .form-textarea  -- multi-line textareas
    .form-help      -- helper text below an input
    .form-error     -- error state block (used both per-field and as a
                      page-level error banner)
    .form-checkbox  -- styled checkbox + label combo

  Load order: tokens.css -> base.css -> shell.css -> components.css
              -> forms.css.

  Version History:
    0.1.2 - 2026-04-27 - Burgundy color migration. .form-error,
                         .form-error-text, .form-input.is-error,
                         and .form-label-required all updated to
                         consume the new red token set
                         (tokens.css 0.1.2). Hardcoded
                         rgba(255, 100, 80, ...) coral references
                         removed. `color: var(--red)` corrected to
                         `var(--red-text)` for legibility -- burgundy
                         is unreadable as foreground text on dark
                         surfaces.
    0.1.1 - 2026-04-27 - Session 3 cont'd. Readability floor pass:
                         - .form-help 12px -> 13px
                         - .form-error 13px -> 14px (banner-level body)
                         - .form-error-text 12px -> 13px (per-field)
                         - .form-checkbox-label small 12px -> 13px
                         - .form-label stays 12px (display small caps)
                         - .form-legend stays 12px (display small caps)
                         Touch override already covered the input
                         font-size at 16px (prevents iOS auto-zoom).
    0.1.0 - 2026-04-27 - Session 3 initial. Form patterns extracted
                         from JQiq lines 636-724 (the most complete
                         and modern form treatment in the source apps,
                         including the autofill kill rule and the
                         Firefox password-reveal fix). iOS date input
                         width fix from RIQ 2.26.0 carried forward.
                         Custom select chevron SVG inlined as data-uri
                         (one of the few places the platform
                         hardcodes a color -- the chevron color
                         matches --text-primary at 85% opacity).
