   Contact form — static HTML mockup styled with our brand.

   At HubSpot port time, this form gets replaced with a HubSpot
   embed (`hbspt.forms.create({...})`) and the CSS adapter layer
   bridges these classes to HubSpot's generated classes:

     .gs-wgs-form__input   → .hs-input
     .gs-wgs-form__field   → .hs-form-field
     .gs-wgs-form__submit  → .hs-button.primary
     .gs-wgs-form__title   → .hs-form .hs-richtext h3

   See skills/why-giant-swarm/SKILL.md §6.7.

   White card w/ subtle grey border, comfortable padding. Inputs
   are pill-shaped to match the site's button language. Labels
   are visually hidden (placeholders carry the label visually);
   labels stay in the DOM for screen readers.

/* ============================================
   HubSpot form embed adapter

   When a use-case page contains {% form form_to_use="..." %}, HubSpot
   renders its own DOM with class names like .hs-form, .hs-input,
   .hs-button, etc. Our gs-wgs-form classes do not match HubSpot's
   structure, so the form would render with browser-default chrome.

   The rules below bridge HubSpot's class names to our design tokens.
   Scoped under .gs-wgs-form--hs-embed so they only fire when we
   intentionally place a HubSpot form embed in our markup, not on
   any random hs-form elsewhere.

   Mapping:
     .hs-form                  → vertical flex layout (mirrors .gs-wgs-form)
     .hs-richtext h3           → .gs-wgs-form__title styling
     .hs-form-field            → .gs-wgs-form__field flex column
     label                     → visually-hidden (placeholder carries label)
     .input                    → no wrapper styling (HubSpot wraps input
                                  in an extra div; we ignore it)
     .hs-input                 → .gs-wgs-form__input — pill, padding,
                                  border, focus state
     select.hs-input           → .gs-wgs-form__select — appearance: none,
                                  custom caret background-image
     .hs-button.primary        → .gs-btn--primary — gradient pill button
     .hs-error-msgs            → small red error text below field
