Accessibility

Grand Salon and Rasoi Pairs use native HTML controls for every required action. One navigation transaction restores logical focus after destination changes, browser Back/Forward, and cancelled or confirmed unfinished-table exits. The Salon lifecycle supplies the appropriate control after a classic-study move, answer, Lantern cover, Stack move, restore, and chapter transition. Navakankari and Aadu boards expose complete screen-reader position and line-relationship descriptions plus lettered 44px destination buttons; Pallanguzhi exposes both rows’ seed counts, sowing order, each authored outcome, and lettered 44px starting pits. Stack plinths announce the ordered discs and current top disc; visible geometry is not the only state source.

Sector Sprint has explicit walking, jump, dash, interaction, pause, map and narrated-route controls. Movement stops on release and clears on cancellation, blur, hiding or exit confirmation. Its complete narrated homecoming and guided course help require no precision, motion, sound or visual interpretation. Reduced motion begins in narration and switches an active exploration to narration. Pause holds the foreground clock while conversations remain operable. Unfinished boundary closure or reload records no completion. Native VoiceOver and physical-device acceptance remain separate from automated semantic and layout checks.

The Salon’s visual Pattern and Mirror tasks are entertainment, not equivalent cognitive measurements. Text alternatives preserve operation and state, but no claim is made that an altered presentation measures the same construct.

Operable rule

• Free tiles are the only tiles in the keyboard tab order.
• Each tile announces its kitchen form, numbered layer, and whether it is free, covered from above, blocked on both sides, selected, or settled.
• Selection and removal work with pointer, touch, keyboard, switch-style activation, and programmatic semantic control.
• All tile and toolbar targets are at least 44 by 44 CSS pixels.
• Live status text describes selection, mismatch, match, help, automatic settlement, and closure.
• Visible text names mean recognition does not depend on the illustration.

The profile selector uses native radio controls, visible descriptions, and explicit three- versus four-layer language, so the distinction does not rely on geometry or color alone. Image Drift exposes all three object names in a semantic list and invites imagery or tactile memory; it is always skippable.

Audio is off by default and optional. The brass bloom and board-to-dabba transition are decorative; reduced motion replaces translation and scale with short opacity changes. Precision movement, mental imagery, sound, animation, and vision are not required.

Alternate presentation

The House and Night surfaces are browser-verified at 320×568, 375×812, 414×896, 768×1024, and 1440×900. Coverage includes House keyboard game paths and dialog focus restoration, Sector Sprint touch-sized controls plus complete Action and Narrated routes, Night keyboard pairing, 200% page scale, reduced motion, target size, visible focus, and horizontal overflow.

Real-device VoiceOver and TalkBack acceptance remains an untested release limitation. Automated semantic checks are not a substitute for that human proof.
