/* ==================================================================
   Threshold
   Engagement / next-step plugin for the Esselith suite
   ------------------------------------------------------------------
   Sitewide floating "Next Steps" button + cream next-step modal.
   All color is variable-driven (--thx-*).
   Fonts: Playfair Display (display) + Montserrat (body).
   (No version here — the version lives ONLY in threshold.php, where
   release.sh checks it. A fact not stated cannot go stale.)

   Esselith Core token layer (#20, step 4): the brand color var
   (--thx-primary) and the font vars alias the suite-wide --es-* tokens,
   with the pre-Core value as the fallback — so with Core deactivated
   Threshold renders exactly as before (Core is an enhancer, never a
   dependency). threshold.php still prints a :root inline block AFTER this
   file that sets --thx-primary from the shared pulpit_suite_brand_primary
   option, so a church's saved brand color applies with or without Core.
   The darkened hover/eyebrow tone (--thx-primary-deep) is derived from the
   brand in CSS so it tracks any brand. The cream panel + ink are suite
   NEUTRALS kept Threshold-local (no --es- alias — there is a matching
   --es-surface/--es-ink, but Threshold preserves its own saved values via
   the inline block, exactly how Credo kept its deep-blue bookends).

   Breakpoint standard (Esselith Core): 600 phone / 782 tablet / 1024
   desktop. Threshold uses 600 (standard) plus a documented 460 narrow-phone
   exception where the two-up option grid genuinely needs to stack.
   ------------------------------------------------------------------
   v1.0.9 — Canon/AAA pass (Esselith design canon; Roger signed off
            each judgment call 2026-07-21). Light-surface orange text
            fails contrast on cream (2.29:1), so: title accent word +
            eyebrow -> teal (the suite workhorse; new --thx-secondary
            token, Core-less fallback #004F71); eyebrow to the canon
            13px/700/0.14em; muted subtexts deepened to clear AAA 7:1;
            outline/text inline buttons -> teal (they were darkened-
            orange text at 3.48:1, and canon makes secondary buttons
            teal anyway). KEPT deliberately: every ink-on-orange fill
            (FAB, primary tile, solid button = the canon CTA pattern),
            the decorative resting tile icons (labels carry meaning;
            hover state is solid orange + ink), and all theme-defense
            !important pins.
   v1.0.5 — Theme-defense (cont.): the modal option words turned orange
            on hover. The options are <a>, and `.thx-option-label` had no
            explicit color, so it inherited the anchor color — which LIVE
            Astra's link hover recolors to its accent (#c97700). Pinned the
            label `color` to the ink !important. Also pinned the inline
            shortcode buttons' background/color/border-color !important
            (same bare-<button> defect as the FAB: Astra's button:hover/
            :focus sets all three to its accent). Hid on dev (default-blue
            Astra). No brand/behavior change.
   v1.0.4 — Theme-defense (cont.): pin the modal close (✕) button's
            background + ink with !important against the same global
            `button:focus` rule. open() focuses the ✕ on modal open, so
            LIVE's Astra painted button:focus with its palette accent
            (amber #c97700) over the faint-ink fill; .thx-close (single
            class) lost to button:focus. Its :hover tint is pinned too so
            the hover cue still shows. Hid on dev (Astra accents :hover,
            not bare :focus). Mirrors the v1.0.3 FAB fix.
   v1.0.3 — Theme-defense: pin the floating button's brand fill + ink with
            !important so a theme's global `button:hover/:focus` rule (Astra's
            button system, lightbox focus blanking) can't recolor the pill on
            hover. .thx-fab is a single class and lost to `button:hover`.
   v1.0.2 — Esselith Core token-layer wiring: --thx-primary → --es-brand-
            primary, --thx-primary-deep → --es-brand-primary-dark (CSS-
            derived so it follows any brand), fonts → --es-font-*. Scrim
            brand wash now lightens-before-alpha (--thx-glow-base) so the
            warm halo survives a dark brand instead of vanishing.
   v1.0.1 — Dropped the -webkit-mask-image hack (it cropped the logo
            on the floating pill); added an orange hover state to the
            light option tiles and brightened resting option icons;
            logo now sized within a max-height / max-width box so any
            aspect ratio scales without cropping.
