/* ==========================================================================
   V4 "Tona" final rebuild — lp/assets/mockup-v4-final.png
   Layout rules here are THEME-AGNOSTIC (apply to any `.v4-root`, so a
   future `.v4-sma` theme pass can reuse this same file's structural rules
   and only add its own color/typography block below). All Tona-specific
   color/typography/decoration is scoped under `.v4-tona` and consumes
   ONLY tona-tokens.css variables/primitives — no hex/hardcoded color here
   outside that scope. See DESIGN_SYSTEM.md for the DA law this encodes.

/* ---------------------------------------------------------------------
   Theme: SMA (ScoreMyAds / Google palette — source: design.md §2 tokens,
   §3 patterns). Same theme-agnostic `.v4-*` markup as Tona above, only
   color/typography/decoration differs. `.tona-btn`/`.tona-card`/
   `.tona-mono` are the shared, theme-agnostic-BY-NAME primitives used
   directly in the v4 markup (see the big architecture comment above
   renderSalesPageV4 in app.js) — their base rules live in tona-tokens.css
   at :root scope, so this theme overrides them here under `.v4-sma` with
   higher selector specificity (2 classes > 1) rather than duplicating the
   markup with sma-*-prefixed classes.

   sma-tokens.css defines its hex/shadow tokens scoped under `.sma-root`
   (the old standalone SMA page's wrapper), which this `.v4-root.v4-sma`
   tree never carries — so those custom properties aren't visible here.
   Rather than re-scope that file (risking the still-linked-but-now-dead
   renderSalesPageSMA() page, kept for parity — see app.js), this block
   mirrors the same hex literals locally as `--v4sma-*` variables, one
   read pointing back to design.md/sma-tokens.css as the source of truth.

/* ---------------------------------------------------------------------
   Theme: Copilot (CommandBar-AI-page-inspired, ?design=v3). Same
   theme-agnostic `.v4-*` markup as Tona/SMA above, only color/typography/
   decoration differs. Signature DNA: warm cream background, lavender/
   purple brand accent (#7B6EF6), dark near-black PILL CTA (radius 100px)
   with a purple glow on hover (not a purple fill — purple stays an
   accent/glow color, per the CommandBar reference), very-rounded
   (26px) floating white cards with big diffuse purple-tinted shadows,
   a stacked-card "ghost layer" motif behind the hero + offer cards
   (via layered solid-color box-shadow copies — no extra DOM/pseudo-
   elements needed, so ghost-card corners can't get clipped by an
   ancestor `overflow: hidden`), and soft purple radial-gradient orb
   halos behind the score gauge and the offer card (via ::before, the
   only pseudo-element budget spent on this theme since the ghost stack
   above uses box-shadow instead of ::before/::after).
   Reuses the global General Sans / Geist Mono `--font-*` tokens from
   tona-tokens.css (:root-scoped, not Tona-theme-scoped) — no new
   fonts, no new @font-face. Functional score-band colors stay
   conventional (red/amber/green) for legibility, each blended 25%
   toward the brand purple so they still read as "this theme" — purple
   itself is reserved for brand chrome (pills, CTA glow, borders, halos),
   not overloaded onto the pass/fail semantics.
