/* ================================================================
   IRONCHILD-WEBSITE — visual language.

   2026-08-21, sixth pass: reverted from the literal-mockup adoption
   (internal Core-panel sidebar + numeric telemetry) back to the
   restrained, honest composition — the architect's own explicit
   instruction after seeing the mockup rendered. The Real Core lives in
   its own full-width section (see css/real-dashboard.css) with
   qualitative states, not numbers; Core Modules stays an icon-first
   system view with no per-category color-coding or counts; Use Cases
   and Story stay unboxed. The only genuinely new element this pass is
   a single "Subscribe" action in the header bar, which the previous
   honest version did not have (its header was plain text nav links
   only) — wired to the same real #pricing/sign-up flow as every other
   CTA on the page, nothing new on the auth/Stripe side.

   Icon language stays Font Awesome throughout — the one real icon
   library, used consistently, never mixed with another family.

/* Confirmed root cause of the auth block "visual enredo" (2026-08-22):
   [hidden] and .auth-form both have specificity 0-1-0. .auth-form sets
   display:flex, which - at equal specificity - beats the browser's own
   [hidden]{display:none} default per normal cascade rules (author styles
   win ties over UA styles). Result: #signupForm's `hidden` attribute was
   silently ignored, so the Sign In form and the Create Account form
   (Email/Password twice, Full Name, Confirm Password, both submit
   buttons) rendered stacked on top of each other on every page load -
   not a spacing/container problem, an actual double-visible-state bug.
   This single rule makes `hidden` unconditionally win everywhere on the
   site, present and future, regardless of any class's own display value. */
