/* ──────────────────────────────────────────────────────────── Section 3 - The Solve (v3) Updated per the Schematic Hotspot brief + follow-up edits: • Two-column layout (60% text panel / 40% schematic) • 7 numbered hotspots, ids 01–07 (consecutive) • Markers sit OFF the drill image, connected back to the component via a subtle 1px leader line (#EDEAE2 @ 0.7). Lines alternate length to create visual rhythm. • Single-active-panel pattern; default active = "01". • Staged intersection-observer reveal (image → leaders → markers → panel → active body). State model: a single string `activeId` ∈ {01..07}. All visual state on markers and panel entries derives from it. No marker can be deselected; Esc returns to "01". ──────────────────────────────────────────────────────────── */ /* ── Subsystem content ───────────────────────────────────── Source: Axion Feasibility Study v1.0 (Dec 2025) - copy verbatim from Axion_Schematic_Hotspot_Copy_v2.md. Coordinate model (% of the schematic image box): • cx, cy - origin: where the leader line starts, just outside the drill body. • mx, my - marker position (where the numbered dot sits). The leader line is drawn from (cx,cy) to a point ~2% short of (mx,my) so there's a small visible gap between the line and the circular hotspot. Hotspots alternate sides - odd ids (01, 03, 05, 07) sit to the RIGHT of the drill, even ids (02, 04, 06) sit to the LEFT. */ /* Spec rows are [LABEL, VALUE] or [LABEL, VALUE, "redacted"].
