RATIO       = infer_canvas_ratio(WORD)

// ── HARD CONSTRAINTS ───────────────────────────────────────────
1. WORD must be a single word, uppercase, 4–10 letters
2. TYPEFACE must support tapering without breaking
3. VERTEX warp applies to upper vertices of central letters only
4. ANCHOR must be a flat-vector silhouette matching $ TOPIC
5. ANCHOR silhouette's interior must not overlap letter ink
6. Palette is strictly 2 colors: solid black, warm cream
7. No drop shadows, no gradients, no lighting, no texture
8. Margins around mark: 15–20% of frame
9. No frame, no border, no extra text
10. Mark must read at 100px, 200px, and 1000px

// ── BUILD SETS ─────────────────────────────────────────────────
LETTER_SET = load_and_layout(WORD, TYPEFACE, baseline, x_height)
WARP_SET   = for each central letter: extend_upper_vertices(VERTEX)
ANCHOR_SET = place_anchor(ANCHOR, at=tip_of(WARP_SET), orientation=symbolic)
NEGATIVE_SET = ensure_no_overlap(LETTER_SET, ANCHOR_SET)
MARGIN_SET = enforce_margins(0.15..0.20)

// ── ASSEMBLY ───────────────────────────────────────────────────
logo = union(
    BACKGROUND_SOLID(CREAM),
    LETTER_SET in BLACK,
    WARP_SET in BLACK,
    ANCHOR_SET in BLACK
)

// ── VALIDATION ─────────────────────────────────────────────────
verify: word reads at 100px
verify: anchor reads at 100px
verify: silhouette does not merge into letter stems
verify: palette exactly 2 colors
verify: no shadows, no gradient, no texture
verify: no logos, no watermarks, no accidental text
Output: 8K vector logo, 1:1 or 4:5.
