1## MODIFIED Requirements23### Requirement: Authored proof titles SHALL remain visible in scene HUD regions45The presentation SHALL render an authored proof title without an ellipsis or6discarded words. In the Proof HUD, it SHALL measure the space between the7`[NN]` number tile and the step counter, subtract 16px from each side, start8at 22px, and shrink in 1px steps to a 16px minimum before wrapping at word9boundaries into at most two lines. On a narrow screen where those two 16px10lines still overflow beside the counter, the title SHALL use the full band11from its left inset to the right inset for up to three 16px lines. In that12fallback, `PROOF NN OF NN` and a compact, right-aligned `STEPS 02` counter13SHALL share the subline row. INDEX banners and Win cards SHALL use the same14shrink-then-wrap helper with their own measured regions. Text fitting SHALL15not change integer grid coordinates, simulation state, or pointer hit16rectangles.1718#### Scenario: A normal Proof title stays on one line1920- **WHEN** a Proof title fits between the number tile and step counter at21 22px with the 16px side insets22- **THEN** the HUD renders the complete title on one line and keeps the23 existing subline and board placement2425#### Scenario: A long Proof title shrinks before wrapping2627- **WHEN** the complete authored title does not fit at 22px but fits at a28 size between 16px and 21px29- **THEN** the HUD renders the complete title on one line at the largest30 fitting integer pixel size and adds no ellipsis3132#### Scenario: A long modded title wraps at word boundaries3334- **WHEN** the complete title still does not fit at 16px35- **THEN** the HUD renders every authored word across no more than two lines,36 breaks only between words, and adds no ellipsis or clipped replacement when37 that two-line fit fits beside the counter3839#### Scenario: A narrow title uses the full mobile band4041- **WHEN** two 16px lines still overflow beside the step counter at 390px42- **THEN** the HUD gives the complete title the full band for up to three43 16px lines, places `PROOF NN OF NN` left and compact `STEPS 02` right on the44 same subline row, and adds no ellipsis or clipped replacement4546#### Scenario: A wrapped Proof title preserves board clearance4748- **WHEN** the Proof title uses two or three lines49- **THEN** the `PROOF NN OF NN` subline and board shift down together and the50 measured HUD-to-board gap remains at least 40px without changing cell size51 or object coordinates5253#### Scenario: INDEX and Win use the shared fitting rule5455- **WHEN** an INDEX banner or Win card receives a title that needs shrinking56 or wrapping57- **THEN** that scene uses the shared shrink and word-boundary wrap helper58 within its own measured region, with complete copy and no ellipsis5960#### Scenario: Mobile fitting remains inside the viewport6162- **WHEN** a long title is rendered at 390x84463- **THEN** its lines remain inside the scene's title region, the board or card64 content retains its safe gap, and existing pointer targets remain unchanged6566#### Scenario: Reduced motion shows settled fitted copy6768- **WHEN** reduced motion is enabled while a title is long enough to shrink or69 wrap70- **THEN** the complete fitted title and any required wrapped layout appear71 immediately with no intermediate clipping or transition-only omission7273#### Scenario: Fitting is presentation-only7475- **WHEN** a title is measured, shrunk, or wrapped76- **THEN** the engine state, level IDs, integer grid coordinates, navigation,77 and pointer hit rectangles are unchanged
