Struct DrawOutput 

pub struct DrawOutput {
    pub biscuit_rect: Rect,
    pub biscuit_focal: (u16, u16),
    pub powerup_rects: Vec<(u64, Rect)>,
    pub play_area: Rect,
    pub upgrade_rows: Vec<(usize, Rect)>,
    pub fingerer_rows: Vec<(usize, Rect)>,
    pub help_hits: Vec<(HelpAction, Rect)>,
    pub prestige_reset_rect: Rect,
}

Per-frame layout snapshot produced by draw. Single source of truth for every clickable region on screen + the play-area envelope.

The platform shells (app.rs, wasm_app.rs) store this verbatim and call crate::input::InputContext::from_layout to project it into the per-event input context. Adding a new clickable region only touches this struct + InputContext + the projection — never the platform code.

Fields

biscuit_rect: Rect

biscuit_focal: (u16, u16)

Screen position of the biscuit’s focal cell (“the asshole”). Each zoom level’s art has the focal at a slightly different offset inside its bounding box (TINY: col 7 of width 16, FULL: col 31 of width 60, etc.), so the bbox center isn’t the visual center. This drives hands::draw’s orbit center.

powerup_rects: Vec<(u64, Rect)>

(spawn_id, screen_rect) for every on-screen powerup, in render order. Click hit-test and the g hotkey BOTH reference instances by spawn_id (not by Vec index) so a swap_remove on catch is safe even when multiple events hold layout snapshots between frames. Empty when no powerups are visible.

play_area: Rect

The whole left column where the biscuit + hands + particles live — i.e. “the box that displays the ass.” Used by the input router so the scroll-wheel zoom fires anywhere in this region (including the vast empty space around a small biscuit at low zoom), and only the right-hand sidebar opts out of zoom.

upgrade_rows: Vec<(usize, Rect)>

(upgrade_idx, screen_row_rect) pairs for the Upgrades panel — populated only when the active mode renders that panel; empty otherwise. The click router hit-tests these for BuyUpgrade. First element of each tuple is also the digit-shortcut target, kept aligned with visible_upgrades.

fingerer_rows: Vec<(usize, Rect)>

(fingerer_idx, screen_row_rect) for the Game-mode sidebar.

help_hits: Vec<(HelpAction, Rect)>

(action, rect) for every clickable help-bar hint at the bottom of the play column. Mouse-first players use these to switch panels, catch goldens, prestige-reset, and quit — all of which used to be keyboard-only. Empty rects when the hint is non-actionable (e.g. [Space/Click] finger is informational, not a click target).

prestige_reset_rect: Rect

Click rect for the Press [r] to reset and claim confirm line in the Prestige panel. Default rect when not in Prestige mode or no prestige is available.
