/* ============================================================
   ARECH Megamenu block — front-end styles.

   Port of the NAV system in
     prototypes/navbar-explore-2026-05-19/nav-4-megamenu-full.html
   re-tokenized to the theme tokens (main.css :root) and corrected to the
   responsive standard (responsive_manual_en_0.1: min-width ONLY, no
   max-width media queries; canonical container box).

   ALL rules are scoped under `.arech-megamenu` so nothing leaks into the
   theme. The bar links sit inline next to the theme logo (the theme <header>
   provides the sticky surface + blur); only the panels / scrim / overlay are
   position:fixed and anchored at top:var(--header-height).

       position:relative + z-index here lift the triggers above the scrim so a

/* -------- SCRIM -------- */
/* ROOT-CAUSE FIX (S74 flicker): the scrim must NEVER cover the nav band.
   Triggers live inside the theme's `.site-header` (a sticky z-index:100 stacking
   context); the scrim + panel are children of that same header, so the scrim's
   local z-index:98 sits ABOVE the triggers (which have z-index:auto). With the
   old `inset:0` the scrim therefore covered the trigger row at y=40, stealing the
   hover off the trigger → mouseleave → close → mouseenter → open → flicker
   (rendered-DOM proof: elementFromPoint(533,40) returned `.arech-mm__scrim`).
   Anchoring the scrim's top at the header height removes the cause: triggers are
   never under the scrim regardless of stacking context, and visually the dim
   correctly begins below the crisp top nav (matches the prototype intent —
   nothing to dim behind a top-anchored nav). Belt-and-braces with the trigger
   z-index lift below (restores the prototype's z-100-nav > z-98-scrim invariant). */

   The package ships its OWN token set so it works standalone on any Concrete

   Kit dashboard overrides any of these at :root per site, re-skinning every
   block at once.

   Defaults below are seeded from the ARECH design-system-v1 (dark theme) as
   the first consumer; on a new site, set the Brand Kit and these are replaced.
   On ARECH you may also map a token to the live theme variable, e.g.
   `--tdm-color-accent: var(--orange);` so the library tracks the theme.

/* ── Universal band tone (spec §1b / §1e — cascade layer `base`) ────────────
   ONE place that re-tones EVERY .tdm-block for a light or dark band, replacing
   the per-block [data-band] ink hooks. The view emits data-band only when the
   band resolves to LIGHT (auto-detected light solid bg, or d_band=light) or to
   a FORCED dark (d_band=dark on an unknown image/gradient bg). Default
   (dark-first site, no attribute) is byte-identical to today.

   Flips ONLY the two universal ink vars (--tdmx-heading / --tdmx-text) that
   Family-A blocks consume; accent (orange) is intentionally untouched — it
   reads AA on both cream and dark. Ink-on-light is derived from the surface
   token via color-mix (no magic hex):
     heading = full surface ink (#0D0D0F-equivalent, ~16:1 on cream)
     body    = surface 78%      (mirrors the S106-tuned value, ~7:1 on cream)
   No !important; single attribute-selector specificity so an explicit
   per-instance .tdm-i-<bID> colour rule from CssEmitter still wins.

   TDM Media + Text — image + text split band (portable port of arech_media_text).
   Tokens come from the package tokens.css (--tdm-*); Design-controlled props
   consume var(--tdmx-*, <fallback>) so a control left at its default keeps this
   CSS fallback (emit-only-on-change).

   The .tdm-block wrapper (base.css) already drives outer padding/margin,
   max-width, alignment, background + overlay, the heading colour + heading font.
   This file adds the two-column grid (image left/right + width share), the
   no-image full-width collapse, the text-column styling, and a self-contained
   solid/outline/ghost button look (so the CTA never depends on tdm_button).

   Namespaced .tdm-mt__* classes only — NOT the package-global .reveal class.
   Breakpoints are min-width ONLY (responsive_manual_en_0.1.md): stack → two
   columns at LG 768.

   BAND TONE — light/dark (canonical, per tdm-band-tone-model-v1).
   view.php emits $design->bandAttr() on the wrapper (view.php:105), so these
   rules are LIVE (not inert). Heading + body INK flip FREE via the GLOBAL hook
   base.css:83-99 (--tdmx-heading / --tdmx-text) — NOT re-declared here. This
   block only re-tones what the global hook can't reach: the OWN band fill, the
   media placeholder / video surfaces, and accent-as-TEXT (eyebrow, body links,
   callout number, list markers, outline-button label) via a LOCAL link var.

   PLAIN attribute selectors only — NEVER :where() (0,0,0 loses to the base
   .tdm-mt class 0,1,0 and surfaces stay dark on a light band — the P4 bug).
   .tdm-mt[data-band="…"] = (0,1,1): beats the base class, still loses to the
   per-instance emitter .tdm-block.tdm-i-<bID> (0,2,0) so operator bg wins.
   With d_band=auto the wrapper carries NO [data-band] → none of these match →
   the dark-first default render is byte-identical.

/* ======================================================================
   TDM Feature Cards — Elementor-grade feature/value card grid.

   7 layouts driven by [data-layout]:
     icon-top (default) · icon-left · image-top · image-left · image-bg ·
     numbered · list
   Per-card media: icon chip / responsive <picture> / typeset number / none.
   Named hover effects via .tdm-fc--hover-* : none · lift · grow ·
   border-reveal · media-zoom. Responsive columns per breakpoint from
   [data-cols-m|t|d] (min-width-only ladder, per responsive_manual_en_0.1).

   Tokens come from the package tokens.css (--tdm-*); Design-controlled props
   consume var(--tdmx-*, <fallback>) so a control left at its default keeps
   this CSS fallback (emit-only-on-change). Fallbacks deliberately mirror the
   profile's neutral defaults (pad space-9, gap space-5, align left) so a fresh
   block renders identically whether or not the Design layer emits.

   BACK-COMPAT: the DEFAULT card (icon-top, surface=bordered, no badge, button
   link, h3 title, 3/2/1 cols) is byte-identical to the v1 block — the base
   rules below reproduce the old icon-top look exactly; every new affordance is
   additive and gated behind a [data-*] hook or a non-default media type.

   Light/dark: the band inherits the theme's dark surface tokens by default
   (this site is dark-first). A `[data-band="dark"]` consumer hook is wired so a
   future light-band remap can override the local --fc-* vars in ONE place
   without touching the rules. AA contrast holds in both: ink on surface(-2),
   accent chip on a 14%-tint, badge text on accent.

   Namespaced .tdm-fc__* (NOT .reveal — that is the package-global scroll-reveal
   class whose base state is opacity:0; reusing it would hide content).
   Block-instance scope (--tdmx-* + reveal) is on the outer .tdm-i-<bID>.

/* ======================================================================
   TDM CTA — call-to-action banner.
   Tokens come from the package tokens.css (--tdm-*). Design-controlled props
   consume var(--tdmx-*, <fallback>) so a control left at its default keeps the
   fallback (emit-only-on-change). Namespaced .tdm-cta__* classes only — do NOT
   reuse the package-global .reveal class for any hook.

   The .tdm-block wrapper (base.css) drives outer padding/margin, alignment,
   background + overlay, heading colour + heading font. This file adds the
   eyebrow style, the heading + subtext type scale, the centre/split layouts,
   and a self-contained button look (solid / outline / ghost) so the CTA matches
   tdm_button without depending on that block being on the page.
   ====================================================================== */

/* =====================================================================
   BAND TONE — light / dark (tdm-band-tone-model-v1, §2-own-surface + §2a-link).
   OWN-SURFACE: the band paints its OWN outer fill via --tdmx-bg (the base.css
   .tdm-block { background:var(--tdmx-bg) } lever) so the banner reads on ANY
   parent. NEVER a direct background: on the wrapper (that would suppress the
   operator's per-instance Design bg via the 0,2,0 .tdm-i-<bID> emitter).
   PLAIN attribute selectors (0,1,1) — NEVER :where() (0,0,0 would lose to the
   base .tdm-cta class 0,1,0 => the P4 dark-on-light bug). `auto` (no
   [data-band]) keeps --tdmx-bg transparent => byte-identical dark-first render.

   LOCAL INK re-tone (the S125 bug fix): this block's heading/subtext route
   through the base h2 rule (color:var(--tdmx-heading)) + --tdmx-text, but once
   the per-instance emitter (.tdm-i-<bID>, 0,2,0) sets --tdmx-heading/--tdmx-text
   the GLOBAL [data-band] hook (0,1,1) is out-won and the title renders ~1:1
   (INVISIBLE) on a light band. So — like tdm_callout — we re-tone heading + body
   + accent-as-TEXT LOCALLY on .tdm-cta[data-band="light"] (0,1,1, declared in
   this view.css after base) so the flip cannot be out-ordered. Surfaces use the
   documented #000-on-#FFF recipe (no --tdm-color-paper-* token exists).

   NOT re-toned (correct on BOTH bands): the SOLID button fill
   (--tdm-color-btn-fill + white label, band-independent AA), the orange FILL
   accent (icon-chip bg, outline border, focus ring, ribbon), and the ribbon
   white-on-orange pair.

   ARECH Footer block — front-end styles.

   Port of the FOOTER in
     prototypes/footer-explore-2026-05-19/footer-A-classic.html
   re-tokenized to the theme tokens (main.css :root) and corrected to the
   responsive standard (responsive_manual_en_0.1):
     • min-width media queries ONLY (no max-width);
     • the prototype's --container-wide:1440 inner becomes the canonical
       container box (--container 1140/1200 + --container-px gutter) so the
       footer caps identically to the navbar + page content;
     • subtle white hairlines use color-mix() (modern CSS, S72 direction);
     • small body text uses --muted-accessible / --light for WCAG AA contrast
       (the prototype's flat --muted #6b6b75 fails 4.5:1 on --dark-2).

   ALL rules are scoped under `.arech-footer` so nothing leaks into the theme.
