    "art_style": "Flat 2D vector UI over a near-black charcoal background; no reels, no realistic lighting or gradiented backdrops beyond simple glow/bloom effects on buttons and flame icons. The player token is a small blocky robot/creature sprite (square red head with a black recessed 'screen' face, a glowing white zig-zag mouth line, two dark eye slits, a red X emblem on its torso, thin dark stubby limbs) rendered in a chunky, slightly cartoonish pixel-adjacent style. Fireball hazards are simple teardrop-shaped orange-to-yellow gradient flame icons with a soft radial glow. Palette is dominated by near-black/charcoal panels, white text, and red/orange/amber accents (buttons, risk indicator, flame icon, ladder rung markers). No day/night or environmental scene at all - the game field is an abstract dark grid of tiles with a vertical white ladder rail. Overall mood is a dark, moody 'danger climb' aesthetic (red glows = threat/heat), casual-arcade rather than photorealistic or cinematic. View is a flat frontal 2D layout (no perspective/isometry).",

Note: the provider playbook (documentation/playbooks/turbo.md, wave 210 correction) describes the official brand icon as a WHITE circle with a RED cross on black; what this build's splash actually shows is the inverse colour arrangement (red disc, black X) - flagged as an observation, not resolved here, since the two could be different assets (in-game splash vs. official press icon) or a rendering/anti-aliasing artefact.",

The player picks a bet amount and a risk level (number of hidden fireballs per row), starts the round, then clicks tiles one row at a time from bottom to top. Each surviving click advances the player token one row up a fixed multiplier ladder; the player may Cash Out at any time after passing at least one row, or let the round auto-resolve by completing all 13 rows. Clicking a tile hiding a fireball ends the round with the stake lost.",

Measured by tile-counting on zoomed crops of the idle board (base_game.png); verified directly on 5 of the 13 rows (top rows 8/9/10 tiles and bottom rows 20/19 tiles) with the remaining rows following the same -1 step.",

    "color_dependence": [
      "Risk-level buttons (1-5): selection is signalled primarily by a red fill + glow, but the numeral itself remains identically legible in both selected and unselected states (white number on either dark or red background), and the buttons keep a FIXED left-to-right numeric order, so a colourblind player can still track the active setting by its screen position and by comparing brightness (selected is visibly filled/lit, unselected are outline-only).",
      "Cleared vs. unopened board rows are distinguished mainly by a faint red tint plus the presence/absence of fireball icons (a distinct teardrop SHAPE, not colour alone) and the player token's position - shape and position both back up the colour cue.",
      "The Start Game / Cancel / Cash Out button all use a similar warm red-orange palette, but they are never shown simultaneously and are distinguished by their TEXT LABEL (which differs for each state), so colour is not the only differentiator.",
      "All 13 multiplier value boxes share the same red border/text styling regardless of value - colour carries no additional meaning between rungs (the number itself, not colour, encodes value), so no colour-only ambiguity exists there."

    "text_and_contrast": "Body text is light grey/white on near-black panels throughout (high contrast); numeric values (balance, bet, multipliers, Cash Out amount) are consistently white or light-coloured bold text, never colour-only encoded numerals.",
    "motion_and_flashing": "No strobing or rapid-flash effects were observed in any captured frame; button glows are soft/steady. No win banner exists at all in this build (see mechanics.cash_out.no_win_banner), so there is also no celebratory flashing animation to worry about for photosensitive players.",
    "audio": "A single volume slider is present in Settings (green track/handle); no separate mute-only toggle or audio-cue description was captured beyond the slider itself. No screen reader / spoken-feedback support evidence was found.",
    "motor_input": "All interactions are simple single clicks/taps (bet buttons, risk-level buttons, tile clicks, Cash Out) - no drag, hold, or precision-timing input is required anywhere in this game (unlike some sibling Turbo Games titles that use HOLD TO SPIN or press-and-hold mechanics)."

A win is only provable by the balance counter changing; confirmed via three independent channels per the capture manifest (pixel diff, a DOM query for win/modal/overlay/toast nodes with a proven positive control, and an exhaustive enumeration of game modes/controls showing this is the game's only mode).",
    "Silent loss: the board resets to idle faster than a screenshot can capture any explosion animation; loss is proven via the DOM class 'game-tile _heated' on the clicked tile and an unchanged balance after the click.",
    "The frames named 'bonus_gameplay_steps.png' and 'win_screen.png' do NOT depict a bonus feature or a win banner respectively - both are ordinary base-game states, kept under those filenames only due to the capture workflow, and are catalogued as type=base_game accordingly. There is no bonus buy, no free spins, and no bonus feature of any kind in Fury Stairs.",
    "The bottom 'All Bets'/'Top bets' ticker shows bets from OTHER Turbo Games titles (Turbo Plinko, Dice Twice, Mines, Crash X, Limbo Rider observed) - this is a shared platform-wide feed, not content belonging to Fury Stairs.",
    "Player nicknames shown in the bets ticker (e.g. 'Redundant Swift', 'Whole Barnacle') are randomly generated per session and carry no game-content meaning.",
    "No autoplay feature exists anywhere in this build (confirmed via scene_probe control enumeration and a full-text search of the DOM for the word 'auto').",
    "The demo host/game code is 'stairs', which shares no substring with the catalogue name 'Fury Stairs' beyond the common word 'stairs' itself being absent from the code - flagged per provider defect P-T12 as a likely provider renaming/rebrand pattern, though no direct evidence of an old public name was found in this build.",
    "The RTP booklet does not use the word 'provably fair' anywhere, unlike some sibling titles/marketing claims for this provider - left as an honest gap rather than assumed."

  "unreadable_or_uncertain": [
    "provably_fair: left null - not stated anywhere inside this game's own rules booklet (see mechanics.provably_fair).",
    "Exact stake-deduction timing (at Start Game vs. at first tile click) was not independently re-measured on THIS slot's captures; inferred only from the Cancel rule text and by analogy with the documented sibling Mines (provider defect P-T10). Treat as likely-but-not-directly-verified for Fury Stairs specifically.",
    "The loading-splash badge colour arrangement (red disc / black X, as literally captured here) versus the provider playbook's documented official brand icon (white disc / red X) was not reconciled - both are reported verbatim rather than one being silently 'corrected' to match the other.",
    "Release date, official RTP showcase text, and any secondary/aggregator sourcing were NOT investigated for this pass - this document is built strictly from the 17 captured frames, the manifest's DOM-derived numbers, and direct visual inspection; no external web lookups were performed."
