/* =============================================================================
   BEHOLD ISRAEL · CORE COMPONENTS
   -----------------------------------------------------------------------------
   The shared component layer for EVERY surface. Requires ../tokens.css first.

     marketing pages  →  tokens.css + components-core.css
     product / app    →  tokens.css + components-core.css + components-product.css

   Every class is `.bi-*`. Components are THEME-AWARE: they read semantic
   tokens only, so the same markup renders correctly inside a dark section
   (`data-theme="dark"`, the default) or a light one (`data-theme="light"`).
   There are no `--dark` / `--light` modifiers — put data-theme on the section.

   DENSITY is a modifier, never a second class. One `.bi-btn`, one `.bi-input`,
   one `.bi-chip`, one `.bi-badge`; `--lg / --md / --sm / --xs` (and `--compact`
   on chips and badges) move them from marketing scale to working-tool scale.
   Compact sizes (sm / xs) drop the hover lift and the large CTA glow.

   Motion rule: only transform, opacity, color, background-color, border-color
   and box-shadow are ever transitioned. A blanket "all" transition is banned.

   components-product.css EXTENDS this file (app shell, tables, KPI tiles,
   overlays, product-only button variants). It never redefines a class here.

   8. Alert (display scale)
   ---------------------------------------------------------------------------
   The marketing-scale callout: sign-in notices, form-level errors, "you're
   signed out", "preorders open". Same grammar as the compact `.bi-c-alert`
   (tint fill · status icon · tile radius) grown to the display scale: 14px
   type, 16px 18px padding, a 20px 1.5px-stroke Lucide icon. The ground is
   `--bi-surface-2` with the variant's translucent status tint laid over it,
   inside a 1px hairline, so it reads as one raised step on either tone.
   Deliberate difference from the compact alert: the display alert KEEPS the
   hairline on tinted variants (a marketing page has no app chrome around it
   to give the tint an edge); `.bi-c-alert` drops it to transparent. The tint
   is layered as `linear-gradient(tint, tint) var(--bi-surface-2)` so the
   translucent status token composites over surface-2, not the page.
   Default is neutral; `--info` / `--success` / `--danger` tint it.
     role="status" for info / success · role="alert" for danger.
     .bi-alert__actions holds compact buttons (.bi-btn--sm).
     .bi-alert__dismiss is the optional close (32px ghost square).

   10. Site navigation (display scale)
   ---------------------------------------------------------------------------
   The marketing header's primary nav. Two renderings of ONE menu tree:
     .bi-nav         desktop bar (≥860px) — links, or <button aria-expanded>
                     triggers that open a floating .bi-nav__menu popover
     .bi-nav-drawer  mobile (<860px) — right-side drawer over a scrim, parents
                     are <button aria-expanded> accordions
   State is attribute-driven so the CSS needs no JS to render a specimen:
     [data-open] on .bi-nav__item / .bi-nav-drawer__item / .bi-nav-drawer
     [aria-expanded] on the trigger (rotates the chevron)
     [aria-current="page"] on the active top-level item (link or trigger) — info tint
     html[data-nav-open] locks page scroll while the drawer is open.
   bi-nav.js (data-bi-nav on the header shell) drives the attributes: click,
   hover / focus-within, Escape, outside click, one-open-at-a-time, focus
   return. The header shell itself (sticky bar, logo, Donate) stays page-level.
   NOTE: the drawer is position:fixed — keep it OUTSIDE any header that uses
   backdrop-filter (that property makes the header its containing block).
